Intramuscular Myxoma

Aggressive angiomyxoma (AAM) is a peculiar neoplasm of the pelvic and perineal soft tissues that most commonly affects women. It is composed of loosely arranged, bland spindled to stellate cells embedded in a myxoid matrix punctuated by numerous venule- and capillary-sized blood vessels reminiscent of myxoid liposarcoma (Fig. 4.8). The vascular pattern of AAM lacks the arborizing appearance that is seen in some overtly malignant myxoid tumors. Some morphologic and immunophenotypic features of aggressive AAM also are shared in part by intramuscular myxoma.

Intramuscular myxoma is a slowly growing benign tumor composed of abundant myxoid deposits and fibroblasts (Murphey et al. 2002 Luna et al. 2005). Intramuscular myxomas primarily affect patients 40-70 years old with a female predominance, and...
