Aggressive angiomyxoma of the vulva and vagina. A common problem: misdiagnosis.

Aggressive angiomyxoma (AA) is a rare myofibroblastic tumor, usually affecting young women. Two patients, one with a vaginal and the other with a vulvar mass underwent surgical intervention with different preoperative diagnoses; the former as vaginal cyst and the latter as vulvar hernia. Unfortunately, the pathological evaluation of the specimens revealed aggressive angiomyxoma. Misdiagnosis of this tumor is a common problem.
