RESUMEN
Leiomyosarcoma is a rare and aggressive soft tissue sarcoma originating in smooth muscle cells. There are two forms of primary superficial leiomyosarcomas depending on the origin and prognosis, one derived from the dermis and the other from the subcutaneous tissue of the skin. Middle-aged to elderly men are particularly affected by this type of cancer. Leiomyosarcomas of the head and neck are quite rare, accounting for approximately 3%~10% of all cases. We report herein a case of subcutaneous leiomyosarcoma of the scalp in a 47-year-old female patient.

Leiomyosarcoma is a relatively rare soft tissue sarcoma of smooth muscle derivation. Superficial or cutaneous leiomyosarcomas, which are very rare and account for less than 3% of the cutaneous soft tissue sarcoma, are subdivided into two groups; a dermal form and a subcutaneous form. Cutaneous leiomyosarcoma may occur anywhere on the body, but there is a predilection for the extremities, especially the thighs. However, leiomyosarcoma of the face is exceedingly rare. We present a case of cutaneous dermal leiomyosarcoma on the face.
