Angioleiomyomas of the extremities: report of a case and review of the Mayo Clinic experience

Angioleiomyomas are rare smooth-muscle tumors that occur anywhere in the body. We present the case of a 46-year-old woman with a 3-year history of a painless angioleiomyoma in the right-hand fourth web space with the typical histologic features of tortuous vascular channels and thick muscular walls. In the 39 cases of angioleiomyoma of an extremity treated at the Mayo Clinic, we found a male-to-female ratio of 1:2.2, a mean age of 52 years, and pain as the presenting symptom in 67 percent of the patients. The lesions usually were less than 1 cm in diameter, and they decreased significantly in size with increasing patient age. Simple excision was curative. Angioleiomyoma should be considered in all patients with nodular lesions of an extremity.
