Angioleiomyoma. A clinicopathologic reappraisal of 562 cases.
Five hundred sixty-two cases of angioleiomyoma in our files on soft tissues were reappraised clinicopathologically. There was a preponderance in females with a ratio of 1.7:1. The angioleiomyoma could be separated into three histologic subtypes: capillary or solid (374 cases), cavernous (61 cases), and venous (127 cases) types. Five hundred (89%) occurrences were in the extremities, 48 in the head, and only 14 in the trunk. The tumors caused pain and/or tenderness in 327 cases, in which 262 were of the solid type. In 16 cases, small groups of mature fat cells were demonstrated within the tumor, suggesting the hamartomatous nature of these smooth muscle tumors.
