Aggressive angiomyxoma of the vulva.
A case of aggressive angiomyxoma (AAM) of the vulva is presented. The tumor presented as a slowly growing polypoid mass in the right labium minus near the clitoris. The tumor was treated by wide local excision. The microscopic appearance was that of spindle-shaped neoplastic cells widely separated by a loose myxoid stroma rich in collagen fibers, hyaluronic acid, and prominent irregular-shaped blood vessels. Aggressive angiomyxoma of the vulva must be distinguished from the more common benign and malignant myxoid tumors including myxoma, myxoid liposarcoma, myxoid variant of malignant fibrous histiocytoma, sarcoma botryoides, nerve sheath myxoma, and other soft tissue tumors with secondary myxoid changes. Local recurrence of AAM may be avoided by wide local excision.
