Angioleiomyoma of the lumbo-sacral region with unusual keloid-like collagen fibers.

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.
