ABSTRACT
Abstract Traumatic neuromas are tumors resulting from hyperplasia of axons and nerve sheath cells after section or injury to the nervous tissue1. We present a case of this tumor, confirmed by anatomopathological examination, in a male patient with history of circumcision. Knowledge of this entity is very important in achieving the differential diagnosis with other lesions that affect the genital area such as condyloma acuminata, bowenoid papulosis, lichen nitidus, sebaceous gland hyperplasia, achrochordon and pearly penile papules.

Pityriasis Rubra Pilaris (PRP) is a chronic and rare papulosquamous disorder. Treatment of Pityriasis Rubra Pilaris is based on empiric evidence because of several doubts regarding its etiology and also because of its relative rarity, making randomized studies difficult to perform. Some factors suggest that the metabolism of vitamin A is involved in pathogenesis. We report a case of Pityriasis Rubra Pilaris associated with autoimmune hypothyroidism which presented rapid and complete response after thyroid hormone replacement, without any association with other systemic treatment. In literature there are only three other reports of significant improvement of the lesions after hormonal correction. Deficiency of thyroid hormone inhibits the conversion of carotene into vitamin A, which would be responsible for the occurrence of Pityriasis Rubra Pilaris in this patient.

Introdução: O melanoma é a mais agressiva das neoplasias cutâneas. O entendimento de seu comportamento e o correto diagnóstico permitindo tratamento precoce pode atuar para diminuir a mortalidade. Objetivos: Entender a incidência e o comportamento histopatológico do melanoma maligno cutâneo em quatro hospitais da cidade de São Paulo, sendo um privado e três públicos. Métodos: Comparou-se as características clínicas e anatomopatológicas de 42 pacientes com diagnóstico de melanoma procedentes de serviços do Complexo Hospitalar Edmundo Vasconcelos (CHEV) com outros três serviços de referência em São Paulo: Santa Casa de São Paulo, Hospital do Servidor Público Estadual de São Paulo, Hospital A.C. Camargo. As variáveis analisadas foram: sexo, tipo histológico da neoplasia; o nível de Clark na peça do anatomopatológico e a profundidade de Breslow. Resultados: 54,76% eram do tipo extensivo superficial, 26,19% nodular, 4,76% acral e 2,38% lentigo maligno. Quanto ao nível de Clark, 16,66% nível I, 42,85% nível II, 19,07% nível III e 7,14% nível IV. Quanto ao Breslow, 66,66% nível I, 11,90% níveI II, 7,14% nível III e 14,28% nível IV. Na amostra estudada as mulheres significaram 61,91%. Conclusão: O tipo extensivo superficial foi o mais prevalente, de espessura Breslow nível I e nível de Clark II.
