Clinical Cytology-Pathology Correlation for Diagnosis of Fallopian Tube Prolapse After Hysterectomy
Bibliographic record
Abstract
Introduction: Prolapse of the fallopian tube into the vaginal vault is a rare complication that may occur after hysterectomy (incidence cited around 0.1%). The clinical presentation includes abdominal pain, dyspareunia, post coital bleeding, and/or vaginal discharge. However, some rare cases can be asymptomatic and diagnosed at routine checkup. Pap smears alone can sometimes be challenging and diagnosing fallopian tube prolapse by the means of vaginal cytology is an even rarer occurrence. Methods: We present the case a 47-year old woman who underwent vaginal hysterectomy with abdominoperineal repair due to prolapse; the clinician made note of an uncommon pelvic laxity. During a routine postsurgical Pap smear check-up, atypical glandular cells were reported. The result and comment from the signing out pathologist triggered a vaginal colposcopy and a pelvic ultrasound, followed later by bilateral salpingo-oophorectomy. Results: The postsurgery Pap test showed the presence of atypical glandular cells with morphologic evidence of cilia. The comment mentioned prolapse of the fallopian tube into vagina. The follow-up colposcopy showed tissue at vaginal vault suspicious for fallopian tube prolapse. The biopsied tissue showed polypoid fragments of stroma and ciliated glandular epithelium, consistent with prolapsed fallopian tube. A transabdominal and transvaginal pelvic ultrasound was done that showed unremarkable ovaries; the fallopian tubes were not visualized. Laparotomy with bilateral salpingo-oophorectomy was performed. The specimen showed fallopian tubes with reactive type changes (marked chronic salpingitis and mesothelial hyperplasia) and no evidence of atypia or malignancy. Conclusions: The cytologic diagnosis of fallopian tube prolapse will be challenging without clinical history and definitive histological assessment. The differential diagnosis of atypical glandular cells in Pap smears, particularly atypical ciliated glandular cells, includes vaginal adenosis, endometriosis, primary or metastatic adenocarcinoma, vesicovaginal and uterovaginal fistulae and granulation tissue related to surgery. Fallopian tube prolapse should be considered in the differential diagnosis of the post-hysterectomy cases.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
