摘要

Carcinosarcoma is a rare biphasic tumor combining malignant epithelial and mesenchymal elements, which may occur in several anatomical areas, including the skin, where a total of 42 cases have been reported up to 2005. It occurs primarily in elderly patients on sun-damaged skin, and the lesion either develops rapidly or has been present for years and increases suddenly in size. One case has been described in association with nevoid basal cell carcinoma syndrome. Histologically, the epithelial component can be of epidermal type (basal or squamous cell carcinoma; 57% of reported cases) or adnexal type (spiradenocarcinoma, porocarcinoma, proliferating tricholemmal cystic carcinoma, or matrical carcinoma; 43% of reported cases), while the mesenchymal component can show osseous, cartilagenous, or more rarely, skeletal or smooth muscle differentiation; no differentiation in nerve tissue has been as yet shown.Here, we present a case of cutaneous carcinosarcoma in which the mesenchymal component showed myofibroblastic differentiation at the ultrastructural level. So far, to our knowledge, this type of mesenchymal component has not been described in the literature.
