Summary
A rare case of fallopian tube prolapse presented as a vaginal mass 30 years post-hysterectomy. This condition mimicked aggressive angiomyxoma, highlighting a significant diagnostic challenge.
Area of Science:
- Gynecologic Pathology
- Surgical Pathology
- Reproductive Medicine
Background:
- Post-hysterectomy vaginal vault prolapse is a known complication.
- Rarely, adnexal structures can prolapse through the vaginal apex.
- Distinguishing benign prolapse from malignancy is crucial.
Observation:
- A 68-year-old woman developed a bleeding vaginal mass 30 years after hysterectomy.
- Clinical suspicion of bowel prolapse was not confirmed.
- Surgical resection of the mass was performed.
Findings:
- Microscopic examination revealed a hypocellular, edematous lesion.
- Glandular structures resembled fallopian tube epithelium.
- Marked condensation of eosinophilic fibrils around vessels was noted, mimicking aggressive angiomyxoma.
Implications:
- This case represents an unusual presentation of fallopian tube prolapse.
- The lesion's appearance poses a diagnostic pitfall, potentially mistaken for aggressive angiomyxoma.
- Accurate histopathological diagnosis is essential for appropriate management of post-hysterectomy vaginal vault masses.
