Definition / general
- Turning of tubes inside out, back into vaginal vault or even more rarely into bladder or uterine cavity
Epidemiology
- Rare (less than 100 cases reported), ~80% occur after vaginal hysterectomy (0.5% incidence), presumed due to nonclosure of vaginal vault
- 0.06% incidence after abdominal hystertecomy, less frequent with interposition or colpotomy
- Associated factors include postoperative fever, hematoma formation / failure to maintain adequate hemostasis, poor physical condition, insufficient preoperative vaginal preparation, difficultly with surgical procedure, use of intraperitoneal vaginal drains and packs
Clinical features
- Occurs two months to eight years after surgery
- May present with watery vaginal discharge, lower abdominal pain, dyspareunia
Case reports
- 27 year old woman with peritoneovaginal fistula (Can J Urol 2010;17:5117)
- 35 year old woman (J Midlife Health 2012;3:40)
- Prolapse of fallopian tube into urinary bladder, resembling carcinoma (Arch Pathol Lab Med 1983;107:613)
Treatment
- Surgical excision
Gross description
- Polypoid mass resembling granulation tissue, visible at vaginal apex
Microscopic (histologic) description
- Normal ciliated fallopian tube epithelium with variable surrounding fibrosis, edema, chronic inflammation
Microscopic (histologic) images
Cytology description
- May be seen on Pap smears
- Columnar cells with cilia and sheets of cells with small granular uniform nuclei in an orderly arrangement; also inflammatory cells and reactive atypia (Diagn Cytopathol 2013;41:146)
Differential diagnosis
- Carcinoma (well differentiated): has glands at odd locations
- Cysts of mesonephric and paramesonephric duct
- Endometriosis
- Vaginal adenosis
