ABSTRACT

BACKGROUND: Microcystic adnexal carcinoma (MAC) is a rare, locally aggressive cutaneous neoplasm that commonly occurs on the face. OBJECTIVE: The purpose of this article is to comprehensively review the current literature on MAC pertaining to epidemiology, pathogenesis, clinical presentation, histology, immunohistochemistry, prognosis, follow-up, and treatment. MATERIALS AND METHODS: An extensive literature review was conducted using OVID MEDLINE and PubMed to identify articles relating to MAC. RESULTS: Microcystic adnexal carcinoma typically presents as a skin-colored nodule on the face. The pathogenesis is mostly related to pilar and eccrine differentiation. Histologically, MAC can mimic syringoma, desmoplastic trichoepithelioma, and infiltrative basal cell carcinoma. Diagnosis is challenging because superficial shave biopsies may reveal only benign findings that do not warrant further management. A deep biopsy is mandatory for the correct diagnosis, and Mohs micrographic surgery provides the highest cure rate. CONCLUSION: Microcystic adnexal carcinoma is a locally aggressive disease with histological margins that often far surpass what is clinically suspected. Mohs micrographic surgery is the standard of care for removal of these lesions. Patients with a history of MAC should be examined at least every 6 months for recurrence, metastasis, and development of additional skin cancers.

ABSTRACT

Introducción: El nevo sebáceo de Jadassohn es un hamartoma que afecta a la epidermis, las glándulas ectópicas ecrinas, las apocrinas y los folículos pilosos. Clásicamente se ha descrito asociado a muchos tipos de neoplasias cutáneas. Material y métodos: Analizamos retrospectivamente todos los casos de nevos sebáceos del archivo del Departamento de Anatomía Patológica del Hospital 12 de Octubre de Madrid desde 1986 hasta 2001. Resultados: De los 366 casos estudiados, 207 eran varones y 159 mujeres. La edad media en el momento de diagnóstico fue de 38 años (límites, 2-85). Se extirparon 28 en niños menores de 16 años. En nuestra serie, las cuatro lesiones más frecuentemente asociadas a nevo sebáceo fueron la verruga vírica (4,09%), siringocistadenoma papilífero (3,27%), tricoblastoma (2,18%) y carcinoma basocelular (1,91%). La verruga vírica fue el hallazgo más frecuente en menores de 10 años con nevo sebáceo (edad media: 18,8; límite: 4-44). No se encontraron neoplasias malignas asociadas en menores de 27 años. Discusión: Como conclusión, nuestra experiencia apoya la idea de que la mayoría de las lesiones asociadas a nevo sebáceo en menores de 10 años son verrugas víricas. La presencia de una verruga vírica en un nevo no excluye la posible malignidad del proceso, aunque esta complicación sea poco frecuente en menores de 30 años. Dermatólogos y patólogos deben tener en cuenta estos hechos para mejorar el cuidado de estos pacientes (AU)

ABSTRACT

BACKGROUND: Eruptive syringomas are uncommon eccrine sweat gland tumours. Only 64 cases have been reported in the literature. OBJECTIVE: Clinical findings of 27 patients with eruptive syringomas were reviewed over a 47-year period. RESULTS: The tumours appeared as multiple yellow-brown-coloured papules localized on the neck, anterior trunk, axillae, shoulders, abdomen or pubic area. This disorder occurs more frequently among women, and is frequent in the prepubertal as well as in the postpubertal age. The diagnosis was not clinically suspected in most cases. CONCLUSIONS: Eruptive syringomas have to be considered in differential diagnosis of papular dermatosis at any age.
