An unusual vaginal lump.

A 46-year-old woman presented with a 2-week history of a painless golf ball sized lump in her vagina. Despite transvaginal ultrasound scan, biopsy and MRI, it was only after surgery had been performed that it became clear what the nature of the mass actually was.Immunohistochemistry revealed the lump to be an aggressive angiomyxoma. Follow-up MRI showed residual (or recurrence of) angiomyxoma which was successfully treated with monthly injections of Prostap (leuprorelin acetate), a gonadotropin-releasing hormone agonist. Further MRI showed complete resolution of the lesion.
