Superficial Angiomyxoma of the Vulva: A Case Report

Superficial angiomyxoma is a rare benign mesenchymal tumor that mainly occurs in the genital region. We report the case of a 51-year-old woman with a painless vulvar mass, well circumscribed on ultrasound. On gross finding, it was a polypoid and bilobed mass, partially encapsulated. On histological examination, it was a proliferation of non-atypical spindle cells with an abundant, myxoid stroma and numerous medium-sized blood vessels. The diagnosis was superficial angiomyxoma. The clinical features do not often lead to the diagnosis of superficial vulvar angiomyxoma. It is based on histological examination and immunohistochemistry is helpful to differentiate it from other myxoid tumors.
