Case for diagnosis. Verrucous plaque on the pubic region.

Muir-Torre syndrome is a rare, autosomal dominant genodermatosis, characterized by sebaceous neoplasms and visceral carcinomas. The authors describe the case of a patient who, 16 years after the diagnosis of colon carcinoma, presented a verrucous plaque on the pubic region, histopathologically compatible with sebaceous adenoma. The need to investigate this syndrome is emphasized, especially in cases of sebaceous neoplasms located outside the head, face, and neck.

Clinicopathological analysis of acral melanoma in a single center: a study of 45 cases.

Objective: The relationship between the clinicopathological and sociodemographics characteristics of acral melanomas diagnosed at the Hospital do Servidor Público Estadual de São Paulo was analyzed and traced between 1997 and 2016.

Methods: An observational, descriptive, and retrospective study of patients diagnosed with acral melanoma was performed at Hospital do Servidor Público Estadual de São Paulo. Sociodemographic and clinicopathological characteristics were collected and analyzed.

Case for diagnosis. Subcutaneous nodules in the plantar region.

The authors report a case of mobile and painful nodules on the bilateral plantar surface of a female patient referred by the rheumatology service, where she was being followed-up for rheumatoid arthritis. A nodule excision was performed for differential diagnosis and symptom relief; the histopathological analysis was compatible with a rheumatoid nodule. Although rheumatoid nodules are a common manifestation of rheumatoid arthritis, exclusive plantar involvement is seldom described in the literature.
