1/2. prolapse of the fallopian tube after hysterectomy associated with exuberant angiomyofibroblastic stroma response: a diagnostic pitfall.We report two cases of prolapse of the fallopian tube associated with an exuberant angiomyofibroblastic stroma response, which occurred after hysterectomy and which is a hitherto unreported feature of this lesion. The tumors were composed of richly vascularized stroma arranged in a retiform pattern and mildly atypical glandular inclusions, which had the morphology of tubal epithelium. The stroma of the lesion was composed of either thin bipolar cells with tapered nuclei and stellate-shaped cells with minimal amount of cytoplasm or small epithelioid-looking cells with eosinophilic cytoplasm. The tubal glandular inclusions displayed mildly atypical nuclear features. If the tubal glandular component was overlooked, these tumors might be erroneously diagnosed as mesenchymal lesions of the vagina, such as vaginal fibroepithelial polyp, angiomyofibroblastoma, aggressive angiomyxoma, or superficial myofibroblastoma.- - - - - - - - - - ranking = 1keywords = angiomyxoma (Clic here for more details about this article) |
2/2. 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.- - - - - - - - - - ranking = 5keywords = angiomyxoma (Clic here for more details about this article) |
