Angioleiomyoma of the lumbo-sacral region with unusual keloid-like collagen fibers
Angioleiomyoma is a benign soft tissue tumor which usually occurs in superficial or deep soft tissues. Only rarely does this tumor occur at unusual sites, including retroperitoneum. We present a rare case of lumbo-sacral angioleiomyoma in a 54-year-old man. Apart from this unusual site, the most str...

Sumario: | Angioleiomyoma is a benign soft tissue tumor which usually occurs in superficial or deep soft tissues. Only rarely does this tumor occur at unusual sites, including retroperitoneum. We present a rare case of lumbo-sacral angioleiomyoma in a 54-year-old man. Apart from this unusual site, the most striking morphological feature was the presence of numerous keloid-like collagen fibers interspersed among the fascicles of the neoplastic cells. Radiological, morphological and immunohistochemical features are presented, and differential diagnosis with its potential morphological mimickers is discussed. |
