Leiomyosarcoma of the skin is most common in middle-aged patients, with a predilection for men (male to female ratio of 2:1). Prior trauma, radiation exposure, and immunosuppression may predispose one to development of leiomyosarcoma. Cutaneous leiomyosarcoma has a favorable prognosis, particularly relative to visceral forms of disease. Some experts have proposed the term "atypical intradermal smooth muscle neoplasm," and disfavor use of the term "sarcoma," to prevent overtreatment of cutaneously limited disease.
