Angiomyofibroblastoma is a rare mesenchymal tumor predominantly of vulvar location. It is characterized being of superficial and slow-growth, low propensity for local recurrence and often misdiagnosed as a Bartholin's gland cyst, hydrocele of the canal of Nuck and aggressive angiomyxoma. A case of vulvar angiomyofibroblastoma in a 56 year-old woman is presented. The specimen was processed by structural and immunohistochemical analysis. It's important to suspect the diagnosis and to distinguish it of aggressive angiomyxoma.
