Abstract: Heerfordt-Waldenström syndrome is a rare subacute variant of sarcoidosis, characterized by enlargement of the parotid or salivary glands, facial nerve paralysis and anterior uveitis. Granulomas with a peripheral lymphocyte deficit are found in the anatomic pathology of affected organs. It is normally self-limiting, with cure achieved between 12 and 36 months, but some prolonged cases have been reported. Diagnosis of the syndrome is clinical, and treatment depends on the degree of systemic impairment. Oral corticosteroids represent the first line treatment option. The mortality rate ranges between 1 and 5% of cases.

Abstract Squamoid eccrine ductal carcinoma is an eccrine carcinoma subtype, and only twelve cases have been reported until now. It is a rare tumor and its histopathological diagnosis is difficult. Almost half of patients are misdiagnosed as squamous cell carcinoma by the incisional biopsy. We report the thirteenth case of squamoid eccrine ductal carcinoma. Female patient, 72 years old, in the last 6 months presenting erythematous, keratotic and ulcerated papules on the nose. The incisional biopsy diagnosed squamoid eccrine ductal carcinoma. After excision, histopathology revealed positive margins. A wideningmargins surgery and grafting were performed, which again resulted in positive margins. The patient was then referred for radiotherapy. After 25 sessions, the injury reappeared. After another surgery, although the intraoperative biopsy showed free surgical margins, the product of resection revealed persistent lesion. Distinction between squamoid eccrine ductal carcinoma and squamous cell carcinoma is important because of the more aggressive nature of the first, which requires wider margins surgery to avoid recurrence.

Summary We report the case of a patient with rheumatoid arthritis who, after 2 months of treatment with etanercept, showed disseminated asymptomatic violaceous papules. Biopsy of the skin lesion showed chronic granulomatous dermatitis with negative staining for fungi and acid-fast bacilli (AFB). After discontinuation of etanercept, the patient's condition improved. Although apparently paradoxical, cases of cutaneous and systemic sarcoidosis after anti-TNF medications have been reported in the literature, with very few cases presenting exclusive cutaneous involvement.
Resumo Relata-se caso de uma paciente com artrite reumatoide que, após 2 meses de tratamento com o medicamento imunobiológico anti-TNF-α etanercepte, apresentou quadro cutâneo compatível com sarcoidose. Notavam-se pápulas violáceas disseminadas e assintomáticas, cuja histopatologia revelou dermatite crônica granulomatosa, com pesquisa de fungos e bacilos álcool-ácido resistentes negativa. Após suspensão do etanercepte, houve regressão do quadro cutâneo. Apesar de paradoxal, têm sido relatados na literatura casos de sarcoidose cutânea e sistêmica após uso de medicações anti-TNF, sendo raríssimos os casos com acometimento cutâneo exclusivo.

Palpable migratory arciform erythema is an entity of unknown etiology, with few published cases in the literature. The clinical and histopathological features of this disease are difficult to be distinguished from those of Jessner’s lymphocytic infiltration of the skin, lupus erythematous tumidus and the deep erythema annulare centrifugum. We describe here the first two Brazilian cases of palpable migratory arciform erythema. The patients presented with infiltrated annular plaques and erythematous arcs without scales. These showed centrifugal growth before disappearing without scarring or residual lesions after a few days. They had a chronic course with repeated episodes for years. In addition, these cases provide evidence of a drug-induced etiology.
