A Case of Lipoleiomyosarcoma in the Spermatic Cord / 대한비뇨기과학회지

A lipoleiomyosarcoma (L-LMS) is an extremely rare tumor, which is a well-differentiated liposarcoma, with leiomyosarcomatous differentiation. Leiomyosarcomatous differentiation may consist of either a well-differentiated liposarcoma, with an intrinsic smooth muscle component, or a dedifferentiated liposarcoma (DL), having smooth muscle differentiation in the dedifferentiated zones. We report an L-LMS appertaining to the latter type, affecting the spermatic cord.
