Aggressive angiomyxoma: A clinicopathologic study of 29 female patients

Abstract

Aggressive angiomyxoma is a distinctive, locally aggressive, mesenchymal tumor that appears to be relatively site specific and has a peak incidence in females in the fourth decade of life. There is a strong propensity for local recurrence but metastatic disease has not been reported. Since the first evidence of recurrence may be many years after the initial resection, long term follow-up is required. The neoplastic cells of aggressive angiomyxoma exhibit fibroblastic and myofibroblastic features and appear to be hormonally influenced. The possibility that the progenitor cell has a capacity for smooth muscle differentiation is raised.
