Abstract

Cutaneous leiomyosarcoma is a rare soft tissue tumor that accounts for 2-3% of all soft tissue sarcomas. Cutaneous leiomyosarcoma can be subdivided into dermal, subcutaneous, and secondary leiomyosarcomas. This subdivision is important because of the different prognosis according to the types. The dermal type of cutaneous leiomyosarcomas are small and grow in the dermis. They rarely metasize, and the prognosis for survival after excision is favorable. We describe a case of dermal type cutaneous leiomyosarcoma on the extensor surface of the right thigh in a 35-year-old man.
