Abstract

Aggressive angiomyxoma (AA), first described by Steeper and Rosai (Am J Surg Pathol. 1983;7:463-475), is a rare locally infiltrative tumor that usually arises in the pelvic and perineal soft tissues of young women. Approximately 150 cases have been reported in women. Aggressive angiomyxoma has a high rate of local recurrence because of its infiltrative growth and anatomical location making complete excision with wide margins difficult. To our knowledge, 39 cases of AA occurring in men have been reported in the literature. Sites frequently involved include the scrotum, spermatic cord, inguinal region, and perineum. The gross and microscopic appearances and clinical course are similar to those described in female cases. Immunohistochemistry evaluating estrogen and progesterone receptors (ER and PR, respectively), although frequently positive in the female cases, has rarely been studied in the male cases. We report the clinicopathologic features of 4 additional cases of AA in men with particular emphasis on hormone (ER/PR) receptor status. Hormone reactivity is significant in that AA may arise from specialized hormonally responsive stromal cells of the perineum and may potentially play a therapeutic role in unresectable tumors. From our small series, hormone positivity (1 case of ER+, 3 cases of PR+) does occur in the male cases of AA, and a large number of cases should be examined to determine the frequency at which these tumors express hormone receptors.
