Low-grade Endometrial Stromal Sarcoma Primarily Arising in the Vagina: A Case Report.
Bibliographic record
Abstract
BACKGROUND: Endometrial stromal sarcoma (ESS) is a rareform of endometrial cancer, comprising < 0.2% of all uterine malignancies and 10% of all uterine sarcomas. To date, the English-language literature contains 6 reports of extrauterine ESS arising primarily in the vagina. We describe the seventh such case, and the first case in which the origin is at the introitus of the vagina. CASE: A 43-year-old, nulligravid, Caucasian woman presented for an annual gynecologic examination and was found to have an asymptomatic 5 x 5-mm, rubbery, soft tissue mass at the 5 o'clock position of the vaginal introitus. As has been reported in several cases of low-grade ESS, this case originated at a site of endometriosis. CONCLUSION: Based on our experience as well as a thorough review of the literature, it appears that early stage low-grade ESS arising in the vagina can be treated effectively with surgical resection followed by close observation for recurrence.

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.
