cutaneous leiomyosarcoma

cutaneous leiomyosarcoma

An uncommon (circa 100 cases reported in the world literature) malignant neoplasm with a predilection for the hair-bearing areas of the lower extremities. Cutaneous leiomyosarcomas are divided into a superficial dermal form, which is thought to arise from the arrector pili muscles, and a deep subcutaneous type, which is thought to arise from the smooth muscle of the vascular wall.
