Abstract: Background: Psoriasis is immune-mediated chronic inflammatory disease with preference for skin and joints. The skin involvement occurs by hyperproliferation and abnormal differentiation of keratinocytes. It is associated with comorbidities, mainly related to the clinical manifestations of the metabolic syndrome. Increased TNF-alpha expression (TNF-α) is related to its pathophysiology. Infliximab is an intravenous drug that acts neutralizing the biological activity of TNF-α and prevents the binding of the molecule to the target cell receptor, inhibiting cell proliferation of psoriasis and other diseases mediated by TNF-α. A lot of infusion reactions have been described in the literature. Objective: To evaluate the adverse effects of intravenous treatment with infliximab, analyzing patients with psoriasis compared to those with other chronic inflammatory diseases (rheumatoid arthritis, ankylosing spondylitis, Crohn's disease and ulcerative colitis). Method: Analysis of medical records and adverse events of 168 patients undergoing infliximab infusion for psoriasis and chronic inflammatory diseases treatment. Results: 168 patients who have used infliximab were evaluated, 24 had psoriasis and 144 had chronic inflammatory diseases. Only 2 (8.3%) patients with psoriasis showed adverse events requiring treatment discontinuation, and just 6 (4.2%) female patients with chronic inflammatory diseases experienced adverse events. Conclusion: Infliximab is a safe drug, with a low percentage of adverse events and there were more adverse events in women with chronic inflammatory diseases and in patients who received more infliximab infusions.

Abstract: Clouston syndrome is a rare genodermatosis that affects skin and annexes. It is a form of ectodermal dysplasia characterized by generalized hypotrichosis, palmoplantar hyperkeratosis and nail dystrophy. This paper reports a 25-year follow-up of a patient with Clouston syndrome, from childhood to adulthood, monitoring diagnosis and clinical course of the disease.

Relatamos um caso de uma paciente de 48 anos com amiloidose sistêmica associada a mieloma múltiplo. Lesões infiltrativas cutâneas como pápulas, nódulos ou placas com aspecto sero-hemorrágico podem ser localizados nas pálpebras, pescoço, região retroauricular dentre outras. No presente caso, as pálpebras foram acometidas por pápulas, há 1 ano, de caráter intermitente e piora após trauma local. Biópsia local evidenciou material amorfo e eosinofílico na derme. A coloração vermelho do Congo confirmou presença de substância amiloide. Exames anormais: proteinúria de 570mg/24 horas, proteinúria de Bence-Jones positiva e mielograma com 70% de plasmócitos atípicos. Assim, realizou-se o diagnóstico de mieloma múltiplo a partir de manifestações cutâneas de amiloidose. Paciente encaminhada ao serviço de hematologia e foi a óbito em 5 meses.

This case report is about a 48-year-old female patient with systemic amyloidosis and multiple myeloma simultaneously. Amyloid cutaneous infiltrative lesions like papules, nodules, or plaques with a serous-hemorrhagic aspect were found in the eyelids, neck and retroauricular region, among others. She had presented intermittent papular lesions on the upper eyelids one year before, which worsened following local trauma. A local skin biopsy showed amorphous and eosinophilic substance in the dermis. Congo red staining confirmed the amyloid deposits. Abnormal exams: proteinuria (570mg/24h), Bence-Jones proteinuria and clonal plasma cells (70%) found in myelogram. Following the diagnosis of multiple myeloma based on amyloid skin lesions, the patient was referred to the Hematology service and died 5 months after the diagnosis.
