Fallopian tube prolapse mimicking aggressive angiomyxoma

A 68-year-old woman presented with a 4-cm polypoid bleeding mass protruding from the vaginal apex 30 years after vaginal hysterectomy. Laparotomy did not confirm the clinical suspicion of bowel prolapse and led to resection of the mass. Microscopic examination revealed a hypocellular edematous lesion with glandular areas resembling fallopian tube epithelium. Condensation of eosinophilic fibrils around medium sized vessels was marked. This case of fallopian tube prolapse shows an unusual resemblance of aggressive angiomyxoma and thus poses a diagnostic pitfall.
