title: Soft tissue angiomyolipoma. A case report.
abstract: A unique case of angiomyolipoma developed in the deep soft tissues of the lower extremity of a 79 year old woman is presented. The initial tumor was misinterpreted as an ordinary lipoma and the recognition of the entity was accomplished only in the recurrent tumor and after the re-evaluation of the slides from the former tumor. The extensive fibroplasia and the bizarre appearance of many proliferating fibroblasts found in the recurrent tumor have been attributed to local host reaction and degenerative changes. However, these changes may create an alarming histologic pattern to the tumor, which need to be differentiated from a lipo- or leiomyosarcoma.
