Cutaneous Leiomyosarcoma: Case Reports and Review of the Literature

Abstract

Two patients with leiomyosarcomas are described, both men with lesions located in the upper trunk. Both lesions were present for more than 10 years. The diagnosis was established after excisional biopsy. The diagnostic criteria are a tumor size greater than 2.5 cm in diameter; a mitotic rate of 1 or more per 5 high-power fields in cellular areas; and electron microscopic verification of smooth muscle cells. The literature is reviewed and the clinical presentation of the 2 patients is discussed. Wide excision is the treatment of choice after histological diagnosis.
