Unusual cutaneous malignancies.
The most commonly occurring cutaneous malignancies are basal cell and squamous cell carcinoma. There are, however, other rare malignancies that are encountered and should be included in the differential, in which both the clinical and the histological diagnosis may be difficult. Here, the clinical and histological features, management, and prognostic factors of merkel cell carcinoma, microcystic adnexal carcinoma, leiomyosarcoma, dermatofibrosarcoma protuberans, and angiosarcoma are reviewed.
