Rapid growing superficial cutaneous leiomyosarcoma of the face

Abstract

Leiomyosarcomas are uncommon malignant smooth muscle tumors, mainly derived from vessels or viscera. Superficial leiomyosarcomas are a rare soft tissue sarcoma arising from the dermis or subcutaneous tissue in the skin. According to tumor origin and location, they are divided into cutaneous and subcutaneous leiomyosarcoma. They have distinctly different histologic and prognostic features from each other. Superficial leiomyosarcomas show a predilection for the proximal extremities and tend to be slow growing. We report one rare case of superficial cutaneous leiomyosarcoma on the right temporal area of face, which showed an extremely rapid growing mass within 3 months.
