Abstract Early malignant syphilis is a rare and severe variant of secondary syphilis. It is clinically characterized by lesions, which can suppurate and be accompanied by systemic symptoms such as high fever, asthenia, myalgia, and torpor state. We report a diabetic patient with characteristic features of the disease showing favorable evolution of the lesions after appropriate treatment.

BACKGROUND: Dermatomyositis affects striated muscles, skin and other organs. OBJECTIVE: To characterize the disease from January 1992 to December 2002, assessing its classification, cutaneous and systemic manifestations, and also laboratory results, therapeutic and prognostic findings compared to those in the literature. METHODS: Data were obtained from medical records of 109 patients who were classified into five groups: 23 juvenile dermatomyositis; 59 primary idiopathic dermatomyositis; 6 amyopathic dermatomyositis; 7 dermatomyositis associated with neoplasms and 14 dermatomyositis associated with other connective tissue diseases. RESULTS: Sixty patients were classified as "definite" diagnosis; 33 as "possible"; four as "probable" and 12 and as amyopathic. The average age at diagnosis was 36 years. Cutaneous manifestations occurred in all patients; the most frequent symptom was loss of proximal muscle strength; the most common pulmonary disorder was interstitial lung disease, and gastritis was the most prevalent digestive manifestation. Tumors were documented in 6.42% of cases. Lactate dehydrogenase was the muscle enzyme most frequently elevated in the majority of cases. Skin biopsies were performed in 68 patients; muscle biopsies in 53; and electroneuromyographies in 58 patients. The most commonly used treatment was corticotherapy and the mortality rate was 14.7%. CONCLUSION: in this sample, the disease appeared in younger individuals, was more frequent in women and the association with cancer was small.

The tumor necrosis factor alpha is a cytokine related to immune and inflammatory processes by acting on different parts of the body. It is secreted by several cell types including macrophages, lymphocytes, monocytes, neutrophils, dendritic cells, among others. Infliximab is a chimeric monoclonal antibody that specifically binds to soluble and transmembrane tumor necrosis factor alpha form blocking its action. In rheumatoid arthritis it is used because the cytokines that cause inflammation in this disease are regulated by tumor necrosis factor alpha and IL-1. We report the case of a 46-year-old patient with rheumatoid arthritis who developed segmental vitiligo after two months using infliximab. The event aims to alert to the existence of this adverse effect that can be induced with the use of this medication.

Define-se o fenômeno de Lúcio como uma variante da reação hansênica do tipo 2. Evento raro, que ocorre na evolução da hanseníase de Lúcio e de outras formas de hanseníase virchowiana. Tem na sua fisiopatologia uma proliferação exacerbada dos bacilos de Hansen, que invadem a parede dos vasos sanguíneos e agridem as células endoteliais, causando proliferação endotelial e diminuição do lúmen vascular, fato este, que associado a reações inflamatórias e a alterações no sistema da coagulação, causa trombose vascular, isquemia, infarto e necrose tecidual, gerando as alterações histopatológicas características do fenômeno. Relatamos um caso de hanseníase virchowiana, com tratamento irregular, que desenvolveu o fenômeno de Lúcio. Recebeu tratamento com poliquimioterapia, antibióticos, corticosteróide e talidomida, evoluindo com desfecho clínico favorável.

Lucio's phenomenon is defined as a variant of type 2 leprosy reaction. It is a rare event, occurring in the evolution of leprosy of Lucio and other forms of lepromatous leprosy. It has an exacerbated proliferation of Hansen bacilli in its pathophysiology, which invade blood vessel walls and injure endothelial cells, causing endothelial proliferation and decreasing the vascular lumen. This fact, associated with inflammatory reactions and changes in the coagulation system causes vascular thrombosis, ischemia, infarction and tissue necrosis, leading to the histopathological characteristic of the phenomenon. We report a case of lepromatous leprosy with irregular treatment that developed Lucio's phenomenon. Treatment with multidrug therapy, antibiotics, steroids and thalidomide achieved a favorable outcome.

Dermatomiosite é doença idiopática inflamatória crônica que afeta a musculatura estriada, a pele e outros órgãos. Apresenta critérios diagnósticos definidos por Bohan & Peter, podendo os pacientes ser classificados em cinco grupos: dermatomiosite juvenil, dermatomiosite primária idiopática, dermatomiosites amiopáticas, dermatomiosite associada a neoplasias e dermatomiosite associada a outras doenças do tecido conectivo. O sexo feminino é mais afetado, e a idade média do diagnóstico é 40 anos. Manifestações cutâneas são observadas em todos os pacientes. Das alterações sistêmicas, a manifestação muscular mais freqüente é a perda de força proximal, e a manifestação pulmonar mais comum é a pneumopatia intersticial. Podem ser observadas neoplasias durante o seguimento da doença, sendo mais freqüentes nos pacientes acima de 60 anos. A desidrogenase lática é a enzima muscular alterada na maioria dos casos. Para diagnóstico da dermatomiosite, pode ser realizado exame anatomopatológico de biópsia cutânea e biópsia muscular, além de eletroneuromiografia. Os corticóides são a terapia mais utilizada. As causas de óbito mais freqüentes são a neoplasia maligna, a septicemia e a infecção pulmonar.

Dermatomyositis is a chronic idiopathic inflammatory disorder that affects striated skeletal muscles, the skin, and other organs. Diagnostic criteria were established by Bohan & Peter and patients may be classified into five groups: juvenile dermatomyositis, primary dermatomyositis, amyopatic dermatomyositis, dermatomyositis associated with malignancies and dermatomyositis associated with other connective tissue disorders. Females are more affected and the mean age of diagnosis is 40 years. Skin manifestations are observed in all patients. Loss of proximal strength is the most common systemic alteration and lung involvement is most often manifested as interstitial pneumopathy. Neoplasms may be detected during the course of the disease specially in patients over 60. Lactic dehydrogenase serum levels are altered in the majority of cases and diagnosis can be established or the basis of skin and muscle biopsies and electroneuromiography. Corticosteroids are the first line drugs. The most common causes of death are malignant neoplasms, sepsis and pulmonary infection.
