Cutaneous Leiomyosarcoma

Abstract

Cutaneous leiomyosarcoma is a rare soft-tissue sarcoma with negligible metastatic potential, but local recurrence rates after surgical excision have ranged from 14 percent to 42 percent. Unlike other sarcomas, guidelines for the optimal surgical excision margin of cutaneous leiomyosarcoma are not clearly defined in the existing literature. A review of local experience with this condition revealed eight patients over 12 years, none of whom developed local recurrence or distant metastases. This is despite poor prognostic factors in seven patients and excision margins ranging from 1 to 27 mm. These findings are compared with previously published data, and conclusions are drawn based on analysis of the collective results. Complete surgical excision with a narrow margin is recommended, and patients should be observed for a minimum of 5 years after surgery. (Plast. Reconstr. Surg. 109: 964, 2002.)
