Angiomyofibroblastoma of the vulva during pregnancy.

Angiomyofibroblastoma is a rare, benign and recently defined soft tissue tumor. It generally arises from superficial soft tissues, especially from mesenchymal cells in the subepithelial myxoid stromal zone of the vulvovaginal region. The tumor is usually positive for estrogen and progesterone receptor. We report a pregnant woman who developed vulvar angiomyofibroblastoma within 2 months. The tumor was negative for estrogen and progesterone receptor.
