Angiomyxoma is a myxoid tumor involving the blood vessels.

Although it is a benign tumour and does not invade neighbouring tissues, it has a tendency to recur after surgical excision so it is termed "aggressive".

Recurrence can occur as early as six months from initial resection.

Patients frequently present at tertiary medical centers with a history of labial mass (sometimes misdiagnosed as Gartner's cyst), with multiple surgical excisions from several surgeons.

There is no standard medical therapy; agents reported to be effective in case reports include systemic hormonal therapy with SERMs such as tamoxifen or LHRH agonists (leuprolide), and cytotoxic ("traditional") chemotherapy, as well as radiation therapy especially for recurrent disease.
