It is characterized by serpiginous white areas around the atrophic mucosa, which alternation between activity, remission and reactivation at various locations gave the names benign migratory glossitis and wandering rash of the tongue. Psoriasis is a chronic inflammatory disease with frequent cutaneous involvement and an immunogenetic basis of great importance in clinical practice. The association between geographic tongue and psoriasis has been demonstrated in various studies, based on observation of its fundamental lesions, microscopic similarity between the two conditions and the presence of a common genetic marker, human leukocyte antigen (HLA) HLA-C*06. The difficulty however in accepting the diagnosis of geographic tongue as oral psoriasis is the fact that not all patients with geographic tongue present psoriasis. Some authors believe that the prevalence of geographic tongue would be much greater if psoriatic patients underwent thorough oral examination. This study aimed to develop a literature review performed between 1980 and 2014, in which consultation of theses, dissertations and selected scientific articles were conducted through search in Scielo and Bireme databases, from Medline and Lilacs sources, relating the common characteristics between geographic tongue and psoriasis. We observed that the frequency of oral lesions is relatively common, but to establish a correct diagnosis of oral psoriasis, immunohistochemical and genetic histopathological analyzes are necessary, thus highlighting the importance of oral examination in psoriatic patients and cutaneous examination in patients with geographic tongue. <![CDATA[Psychometrican analysis and dimensional structure of the Brazilian version of melasma quality of life scale (MELASQoL-BP)]]> Abstract: Background: Although asymptomatic, melasma inflicts significant impact on quality of life. MELASQoL is the main instrument used to assess quality of life associated with melasma, it has been validated in several languages, but its latent dimensional structure and psychometric properties haven´t been fully explored. Objectives: To evaluate psychometric characteristics, information and dimensional structure of the Brazilian version of MELASQoL. Methods: Survey with patients with facial melasma through socio-demographic questionnaire, DLQI-BRA, MASI and MELASQoL-BP, exploratory and confirmatory factor analysis, internal consistency of MELASQoL and latent dimensions (Cronbach's alpha). The informativeness of the model and items were investigated by the Rasch model (ordinal data). Results: We evaluated 154 patients, 134 (87%) were female, mean age (± SD) of 39 (± 8) years, the onset of melasma at 27 (± 8) years, median (p25-p75) of MASI scores , DLQI and MELASQoL 8 (5-15) 2 (1-6) and 30 (17-44). The correlation (rho) of MELASQoL with DLQI and MASI were: 0.70 and 0.36. Exploratory factor analysis identified two latent dimensions: Q1-Q3 and Q4-Q10, which had significantly more adjusted factor structure than the one-dimensional model: Χ2 / gl = 2.03, CFI = 0.95, AGFI = 0.94, RMSEA = 0.08. Cronbach's coefficient for the one-dimensional model and the factors were: 0.95, 0.92 and 0.93. Rasch analysis demonstrated that the use of seven alternatives per item resulted in no increase in the model informativeness. Conclusions: MELASQoL-BP showed good psychometric performance and a latent structure of two dimensions. We also identified an oversizing of item alternatives to characterize the aggregate information to each dimension. <![CDATA[Evaluation of the relationship between c-Kit expression and mean platelet volume in classic Kaposi's sarcoma]]> Abstract: Background: c-Kit is a proto-oncogene that encodes tyrosine kinase receptor (CD117). Mean platelet volume (MPV) is a useful marker, providing information on platelet function and diameter. Objective: To investigate c-Kit expression and intensity in patients with Kaposi's sarcoma (KS) and to investigate the relation between Ki-67 proliferation and MPV. Methods: A total of 32 patients, diagnosed with classic cutaneous KS, were included in this study. We reevaluated the histopathological reports with the preparations, confirmed the diagnosis and then determined the patients' histopathological stages. c-Kit expression and Ki-67 proliferation were investigated immunohistochemically in KS cases, while MPV in all cases was checked. Results: Although c-Kit expression was detected in 22 cases (68.8%), it was not expressed in 10 cases (31.2%). We detected 8 cases with + (25%), 6 with ++ (18.8%) and 8 with +++ (25%). Ki-67 expression was 5.0% (min-max 1.0-20.0). Relapse was observed in 5 cases (15.6%) out of 32. There was positive correlation between c-Kit expression and MPV (rs=0.598, p&lt;0.001), and between c-Kit intensity and MPV (rs=0.588, p&lt;0.001). Conclusion: c-Kit is highly positive in KS. c-Kit positivity indicates a high risk of tumor growth, invasion and relapse. Furthermore, c-Kit expression stimulates megakaryocytes to release young and large thrombocytes into the periphery. Thus, high MPV, c-Kit expression and immunostaining intensity indicate high invasion and relapse in KS subjects. <![CDATA[Mortality due to cutaneous melanoma in south region of Brazil: a spatial approach]]> Abstract: Background: Cutaneous melanoma is a skin cancer with low incidence but high mortality rates. The South region of Brazil has the highest death rates by melanoma per 100,000 inhabitants of the country. Little is known about the spatial distribution of this malignancy in southern Brazil. Objectives: Identify the spatial patterns of deaths from cutaneous melanoma in South region of Brazil, using geoprocessing tools. Methods: This is an ecological and exploratory study of death information by cutaneous melanoma obtained from portal Datasus, for Brazil's southern region, from January 2008 to December 2012. Deaths were separated by gender and rates per 100,000 inhabitants were calculated and used to compile thematic maps, Moran maps and Kernel maps, using TerraView software. It was adopted an alpha = 5%. Results: There were data on 2378 deaths from cutaneous melanoma in the study period. High rates were identified in the northern and littoral regions of Rio Grande do Sul; the northeast of Santa Catarina; and west of Paraná - for the total population, with minor differences detected and indicated regarding gender. The global Moran index presented p-values of 0.03, 0.04 and 0.03, respectively, for male, female and overall deaths. All the micro-regions that showed high priority for intervention were detected in the Rio Grande do Sul. Conclusion: Spatial clusters of micro-regions with high death rates from cutaneous melanoma in South region of Brazil were identified, serving as an important tool for health managers. <![CDATA[Nail abnormalities in patients with vitiligo]]> Abstract: Background: Vitiligo is an acquired pigmentary skin disorder affecting 0.1-4% of the general population. The nails may be affected in patients with an autoimmune disease such as psoriasis, and in those with alopecia areata. It has been suggested that nail abnormalities should be apparent in vitiligo patients. Objective: We sought to document the frequency and clinical presentation of nail abnormalities in vitiligo patients compared to healthy volunteers. We also examined the correlations between nail abnormalities and various clinical parameters. Methods: This study included 100 vitiligo patients and 100 healthy subjects. Full medical histories were collected from the subjects, who underwent thorough general and nail examinations. All nail changes were noted. In the event of clinical suspicion of a fungal infection, additional mycological investigations were performed. Results: Nail abnormalities were more prevalent in the patients (78%) than in the controls (55%) (p=0.001). Longitudinal ridging was the most common finding (42%), followed by (in descending order): leukonychia, an absent lunula, onycholysis, nail bed pallor, onychomycosis, splinter hemorrhage and nail plate thinning. The frequency of longitudinal ridging was significantly higher in patients than in controls (p&lt;0.001). Conclusions: Nail abnormalities were more prevalent in vitiligo patients than in controls. Systematic examination of the nails in such patients is useful because nail abnormalities are frequent. However, the causes of such abnormalities require further study. Longitudinal ridging and leukonychia were the most common abnormalities observed in this study. <![CDATA[Stress level of people with psoriasis at a public hospital]]> Abstract: Background: Psoriasis is a chronic dermatosis of unknown etiology with a tendency to relapse after treatment. The disease is frequently linked to psychological stress due to the embarrassment caused by the lesions. Objective: To analyze the stress level presented by psoriasis patients followed at the Dermatology Service of a public hospital in Salvador, Bahia state, Brazil. Methods: A cross-sectional study of a consecutive convenience sample composed of 60 participants. We used Lipp's Stress Symptoms Inventory for Adults to assess stress levels. The questionnaire identifies and classifies physical and psychological symptoms according to three stages of stress: alarming, resistance, and exhaustion. We also collected socio-demographic and clinical data that could be associated with psoriasis. Results: 85% of the participants presented stress. Lipp's questionnaire results revealed that 48% were in the resistance stage and 37% in the exhaustion stage. Women presented higher levels of stress. Of the total 28 women, 64% were in exhaustion stage, 29% in the resistance stage, and only 7% presented no stress symptoms. Of the total 32 men, 44% were in resistance stage, 34% in exhaustion stage, and 22% presented no stress symptoms. Regarding physical and psychological symptoms, psychological symptomatology was prevalent (55%). Conclusions: Based on the number of patients in exhaustion stage, we can conclude that stress levels of the participants were high regardless the type of psoriasis and treatment duration. <![CDATA[Non-melanoma skin cancer in Portuguese kidney transplant recipients - incidence and risk factors]]> Abstract: Background: Cancer is currently among the three leading causes of death after solid organ transplantation and its incidence is increasing. Non-melanoma skin cancer - squamous cell carcinoma and basal cell carcinoma - is the most common malignancy found in kidney transplant recipients (KTRs). The incidence of non-melanoma skin cancer in KTRs has not been extensively studied in Portugal. Objectives: To determine the incidence of non-melanoma skin cancer in KTRs from the largest Portuguese kidney transplant unit; and to study risk factors for non-melanoma skin cancer. Methods: Retrospective analysis of clinical records of KTRs referred for the first time for a dermatology consultation between 2004 and 2013. A case-control study was performed on KTRs with and without non-melanoma skin cancer. Results: We included 288 KTRs with a median age at transplantation of 47 years, a male gender predominance (66%) and a median transplant duration of 3.67 years. One fourth (n=71) of KTRs developed 131 non-melanoma skin cancers, including 69 (53%) squamous cell carcinomas and 62 (47%) basal cell carcinomas (ratio squamous cell carcinoma: basal cell carcinoma 1.11), with a mean of 1.85 neoplasms per patient. Forty percent of invasive squamous cell carcinomas involved at least two clinical or histological high-risk features. The following factors were associated with a higher risk of non-melanoma skin cancer: an older age at transplantation and at the first consultation, a longer transplant duration and the presence of actinic keratosis. KTRs treated with azathioprine were 2.85 times more likely to develop non-melanoma skin cancer (p=0.01). Conclusion: Non-melanoma skin cancer was a common reason for dermatology consultation in Portuguese KTRs. It is imperative for KTRs to have access to specialized dermatology consultation for early referral and treatment of skin malignancies. <![CDATA[Link between immunoexpression of hMLH1 and hMSH2 proteins and clinical-epidemiological aspects of actinic cheilitis]]> Abstract: Background: The studies found in the literature associate the immunoexpression of hMLH1 and hMSH2 proteins with histologic aspects, but do not correlate it with clinical and epidemiological data. Objective: To evaluate the immunoexpression of hMLH1 and hMSH2 in actinic cheilitis, correlating it with clinical characteristics. Methods: We analyzed 40 cases. Histological and immunohistochemical analyses were performed. The following clinical variables were evaluated: gender, age range, ethnicity, clinical aspect and occupational sunlight exposure. Statistical evaluation included the Student t-test, while the significance level was set at 5%. Results: Greater immunoexpression of hMLH1 and hMSH2 was observed in females, individuals aged over 40, and mixed-race/black patients. Furthermore, the immunoexpression of these proteins was greater in actinic cheilitis with a white-colored appearance and in patients without occupational sunlight exposure. No statistical differences were observed for the variables studied. Conclusion: This study uncovered variations of hMLH1 and hMSH2 protein expression upon evaluation of clinical aspects in actinic cheilitis. <![CDATA[Serum lipid profile and clinical characteristics of patients with xanthelasma palpebrarum]]> Abstract: Background: Although many factors are involved in the etiology of xanthelasma palpebrum, lipid disorder is strongly associated with its induction. Xanthelasma palpebrum, the most common type of xanthoma, usually presents in middle-aged females and results in aesthetic problems. Objective: To evaluate thelipid profile and important clinical aspects of xanthelasma palpebrum patients. Methods: In this descriptive study, we enrolled 42xanthelasma palpebrumpatients, and 42 cases of non-inflammatory skin disorders as thecontrol group, matched for age and gender.The clinical characteristics of the patients and fasting serum lipid profile were recorded for both groups. The data obtained were analyzed using SPSS-16. Results: Xanthelasma palpebrum was found more commonly in middle-aged females with disease onset of less than 1 year, and without significant familial history of xanthoma. Furthermore,xanthelasma lesionswere most often seen in the upper lid with mild extension and was rarely associated with systemic disease. There was no statistically significant difference between two groups regarding hypertriglyceridemia (p= 0.231) and hypercholesterolemia (p= 0.302). The mean serum levels of cholesterol (221.51±60.4 mg/dl), triglyceride (185.98±71.1 mg/dl) and VLDL (37.7±17.6 mg/dl) were significantly higher and themedian HDL (36.2 (31, 41) mg/dl) level was lower in thepatient group. Conclusion: In our study, hypercholesterolemia and hypertriglyceridemia did not reveal a significant difference between thepatient and control groups; however, mean serum values for cholesterol, triglyceride, VLDL and HDL showed a significant difference between the two groups. Therefore, in addition to lipid abnormality, other factors could be involved in the pathogenesis of xanthelasma palpebrum. <![CDATA[Skin barrier in atopic dermatitis: beyond filaggrin]]> Abstract: Atopic dermatitis is a chronic inflammatory skin disease with a complex pathogenesis, where changes in skin barrier and imbalance of the immune system are relevant factors. The skin forms a mechanic and immune barrier, regulating water loss from the internal to the external environment, and protecting the individual from external aggressions, such as microorganisms, ultraviolet radiation and physical trauma. Main components of the skin barrier are located in the outer layers of the epidermis (such as filaggrin), the proteins that form the tight junction (TJ) and components of the innate immune system. Recent data involving skin barrier reveal new information regarding its structure and its role in the mechanic-immunological defense; atopic dermatitis (AD) is an example of a disease related to dysfunctions associated with this complex. <![CDATA[Atopic dermatitis: allergic dermatitis or neuroimmune dermatitis?]]> Abstract: Advances in knowledge of neurocellulars relations have provided new directions in the understanding and treatment of numerous conditions, including atopic dermatitis. It is known that emotional, physical, chemical or biological stimuli can generate more accentuated responses in atopic patients than in non-atopic individuals; however, the complex network of control covered by these influences, especially by neuropeptides and neurotrophins, and their genetic relations, still keep secrets to be revealed. Itching and airway hyperresponsiveness, the main aspects of atopy, are associated with disruption of the neurosensory network activity. Increased epidermal innervation and production of neurotrophins, neuropeptides, cytokines and proteases, in addition to their relations with the sensory receptors in an epidermis with poor lipid mantle, are the aspects currently covered for understanding atopic dermatitis. <![CDATA[Laser therapy in wound healing associated with diabetes mellitus - Review]]> Abstract: The article discusses the results of a literature review on the application of low intensity laser therapy on the healing of wounds associated diabetes mellitus in the last 10 years. Objective: To determine the most effective parameter in healing wounds related to diabetes mellitus, as well as the most widely used type of laser. Methodology: consisted of bibliographic searching the databases Bireme, SciELO, PubMed/Medline and Lilacs by using the keywords related to the topic. Were selected from these keywords, papers discussing the use of laser on wounds associated with diabetes, published in the period 2005-2014, in Portuguese or English. Results: After analyzing the research, 12 studies consistent with the theme were selected. Conclusion: Based on this review, the studies that showed more satisfactory results in healing diabetic wounds were those who applied energy densities in the range of 3-5 J/cm2, power densities equal to or below 0.2 W/cm2 and continuous emission. The He-Ne laser with a wavelength of 632.8 nm was used more often. <![CDATA[Porokeratosis ptychotropica: a rare manifestation with typical histological exam]]> Abstract: Porokeratosis is a disorder of epidermal keratinization characterized clinically by a distinctive ridge-like border, and histologically by cornoid lamellae. The known clinical variants of porokeratosis are: classic porokeratosis of Mibelli, disseminated superficial (actinic) porokeratosis (DSAP), porokeratosis palmaris et plantaris disseminata, linear porokeratosis and punctate porokeratosis. In 1995, a seventh form was described as porokeratosis ptychotropica: a verrucous form resembling psoriasis involving the gluteal cleft presenting on the histological exam multiple cornoid lamellae. There are very few reports in the literature of this clinical variant. The present study describes the case of a healthy male presenting gluteal hyperkeratotic plaques for 22 years. He had been to several dermatologists, none of them had achieved a definitive diagnosis. We present a typical clinical presentation and its dermoscopy findings, in addition to histological examination that confirmed the diagnosis. <![CDATA[Rheumatoid arthritis and pseudo-vesicular skin plaques: rheumatoid neutrophilic dermatosis]]> Abstract: A 54 year-old woman with a 3-year history of rheumatoid arthritis (RA) consulted us because of weight loss, fever and skin eruption. On physical examination, erythematous plaques with a pseudo-vesicular appearance were seen on the back of both shoulders. Histological examination was consistent with rheumatoid neutrophilic dermatosis (RND). After 3 days of prednisone treatment, the skin eruption resolved. RND is a rare cutaneous manifestation of seropositive RA, characterized by asymptomatic, symmetrical erythematous plaques with a pseudo-vesicular appearance. Histology characteristically reveals a dense, neutrophilic infiltrate with leucocitoclasis but without other signs of vasculitis. Lesions may resolve spontaneously or with RA treatment. This case illustrates an uncommon skin manifestation of active rheumatoid arthritis. <![CDATA[Eosinophilic annular erythema in childhood - Case report]]> Abstract: Eosinophilic annular erythema is a rare, benign, recurrent disease, clinically characterized by persistent, annular, erythematous lesions, revealing histopathologically perivascular infiltrates with abundant eosinophils. This report describes an unusual case of eosinophilic annular erythema in a 3-year-old female, requiring sustained doses of hydroxychloroquine to be adequately controlled. <![CDATA[Primary cutaneous plasmablastic lymphoma revealing clinically unsuspected HIV infection]]> Abstract: Plasmablastic lymphoma is a rare subtype of diffuse large B-cell lymphoma more frequently diagnosed in immunosuppressed patients, mainly HIV-infected. Primary cutaneous plasmablastic lymphoma is extremely rare, and in this patient it was the first clinical manifestation of unsuspected HIV-infection. <![CDATA[Linear cutaneous lupus erythematosus following the lines of Blaschko - Case report]]> Abstract: Chronic cutaneous lupus erythematosus in a linear configuration is rare, particularly in children, demonstrating similar incidence in both genders, no photo-sensitivity and lower probability of progression to systemic disease. We describe the case of a 9-year-old girl who presented erythematous papules with central atrophy on the upper and lower right limbs, asymptomatic and following the lines of Blaschko, since age four. Histological examination showed atrophy of the epidermis with aggression from epidermal-dermal interface and periadnexal and perivascular lymphocytic inflammatory infiltrate. Laboratory tests showed ANA in a titer of 1:320, in a dense and fine speckled pattern. Due to the rarity of presentation and location of the disease, this case is reported here. <![CDATA[Melanoma associated with congenital intermediate common blue nevus of the scalp - Case report]]> Abstract: Melanomas can arise either de novo (70%) or from pre-existing melanocytic lesions (30%). Of the latter, most cases arise at the dermoepidermal junction from small congenital or acquired non-blue nevi while only a few arise from blue nevi, notably the cellular subtype and less commonly the common (dendritic) type. Melanomas that arise from blue nevi usually occur on the scalp with greater frequency, as in the case described. Although previous studies have discussed melanoma arising from giant congenital blue nevi, few have discussed those arising from intermediate blue nevi. We present a case of a 52-yearold man with melanoma on the scalp evolving from an intermediate congenital common blue nevus. <![CDATA[Single cutaneous metastasis of colon adenocarcinoma - Case report]]> Abstract: Skin metastases are relatively rare and occur most often when the cancer is already advanced, invading other organs. As to location, they often seem to elect areas located close to the primary tumor, although distant sites, such as the scalp, may be affected with some frequency. We present a case of a 76-year-old woman with colon adenocarcinoma that had a single metastatic lesion on the scalp. <![CDATA[Porphyria cutanea tarda in a HIV- positive patient]]> Abstract: This is a case report about Porphyria cutanea tarda (PCT) and its relationship with the infection caused by the human immunodeficiency virus (HIV). Cutaneous porphyria is an illness caused by enzymatic modification that results in partial deficiency of uroporphyrinogen decarboxylase (Urod), which may be hereditary or acquired. Several studies suggest that HIV infection associated with cofactors might trigger the development of porphyria cutanea tarda. In this case report, we present a patient infected with HIV, who after the introduction of antiretroviral therapy (ART) enjoyed clinical improvement of porphyria cutanea tarda symptoms. <![CDATA[Acute generalized exanthematous pustulosis associated with spider bite]]> Abstract: Acute generalized exanthematous pustulosis (AGEP) is an acute febrile rash, usually induced by drugs, which recently has been linked to spider bite. We report a case of a male patient, 48 years old, with an erythematous rash accompanied by fever and small non-follicular pustules. He reported previous pain in the buttock with the onset of a necrotic plaque. The lesion was compatible with spider bite of the genus Loxosceles. According to the EuroSCAR group instrument, the patient scored +10 indicating definite diagnosis of AGEP. As the patient had a compatible lesion and had no other triggers of AGEP, in an Loxosceles endemic area, the AGEP would be associated with spider bite, as described in other publications. <![CDATA[Nodular tertiary syphilis in an immunocompetent patient]]> Abstract: Acquired syphilis can be divided into primary, secondary, latent, and tertiary stages. About 25% of patients with untreated primary syphilis will develop late signs that generally occur after three to five years, with involvement of several organs. The authors present an immunocompetent female who developed a tertiary stage syphilis presenting with long-standing nodular plaques. <![CDATA[Case for diagnosis. Metastatic Crohn's disease]]> Abstract: Metastatic Crohn's disease is a rare skin manifestation, defined by granulomatous skin lesions that are discontinuous to the affected gastrointestinal tract and histopathologically resembling inflammatory bowel lesions. Up to 44% of patients with Crohn's disease have cutaneous manifestations, of which metastatic lesions are the least common. We present a case of an adolescent with refractory Crohn's disease and persistent papules and plaques on the skin. <![CDATA[Lichen sclerosus associated with localized scleroderma: dermoscopy contribution]]> Abstract: Lichen sclerosus is an uncommon inflammatory dermatosis with preferential involvement of the urogenital region. The extragenital involvement is uncommon and is characterized by small rounded macules or papules, pearly white in color. The coexistence of lichen sclerosus and scleroderma plaques in most cases with extragenital location has been reported in the literature. We report a case of lichen sclerosus associated with scleroderma in children, highlighting the importance of dermoscopy in diagnosis. <![CDATA[Disseminated cutaneous sporotrichosis associated with ocular lesion in an immunocompetent patient]]> Abstract: A 59-year-old female patient, previously healthy, immunocompetent, presented left bulbar conjunctiva lesions and nodular-ulcerated lesions on the arms and cervical region, besides left cervical and retroauricular lymphadenopathy. She had previous contact with domestic cats that excoriated her face. The diagnosis was conclusive of disseminated sporotrichosis through clinical and epidemiological history and cultures of skin and ocular secretions. It evolved with good response to oral antifungal therapy. <![CDATA[Syndrome in question: Gorlin-Goltz syndrome]]> Abstract: The Nevoid Basal Cell Carcinoma Syndrome (NBCCS) is an uncommon disorder caused by a mutation in Patched, tumor suppressor gene. It is mainly characterized by numerous early onset basal cell carcinomas, odontogenic cysts of jaw and skeletal abnormalities. Due to the wide clinical spectrum, treatment and management of its modalities are not standardized and should be individualized and monitored by a multidisciplinary team. We report a typical case in a 30-year-old man with multiple basal cell carcinomas, keratotic pits of palmar creases and bifid ribs, with a history of several corrective surgeries for keratocystic odontogenic tumors, among other lesions characteristic of the syndrome. <![CDATA[Cost comparison of three kinds of compression therapy in venous ulcer]]> Abstract: Evolution and cost of three types of compression therapy (single layer, multilayer and Unna boot) in patients with venous ulceration were compared. The evaluation lasted two months and used photographic records and instrument based on pressure ulcer scale for healing (PUSH). Treatment with monolayer compression therapy presented the lowest cost and more efficacy of the three types, with 82% savings compared with the multilayer therapy. <![CDATA[Leprosy: ancient disease remains a public health problem nowadays]]> Abstract: Despite being an ancient disease, leprosy remains a public health problem in several countries -particularly in India, Brazil and Indonesia. The current operational guidelines emphasize the evaluation of disability from the time of diagnosis and stipulate as fundamental principles for disease control: early detection and proper treatment. Continued efforts are needed to establish and improve quality leprosy services. A qualified primary care network that is integrated into specialized service and the development of educational activities are part of the arsenal in the fight against the disease, considered neglected and stigmatizing. <![CDATA[Clinical, epidemiological and therapeutic profile of patients with brachioradial pruritus in a reference service in dermatology]]> Abstract: This is a cross-sectional study, conducted from May to November/2014, in a dermatology reference unit, through review of medical records and interviews. In a sample of 49 patients with brachioradial pruritus, we observed higher prevalence of Caucasian (81.6%) and women (73.5 %), with a mean age of 56.1 years. Pruritus occurred in the topography of brachioradialis muscle in 87.8% of cases; 59.2% of the sample reported worsening of pruritus with sun exposure; the mean intensity of this symptom before treatment was 8.63. Therapy effectiveness was described as "very good/good" in 79.2% of cases, and for 55.3% relapses were categorized as "uncommon". <![CDATA[Coexistence of granuloma annulare and chronic spontaneous urticaria]]> Abstract: This is a cross-sectional study, conducted from May to November/2014, in a dermatology reference unit, through review of medical records and interviews.
