β-hCG secreting uterine PEComa
Bibliographic record
Abstract
A postmenopausal female patient presented with vaginal bleeding. Initial bloodwork revealed an elevated serum beta human chorionic gonadotropin level (β-hCG). Pelvic MRI identified a complex heterogeneous uterine mass with central necrosis. She underwent total abdominal hysterectomy with bilateral saplingo-oopherectomy. Pathology reported a malignant perivascular epithelioid cell tumour (PEComa). Postoperatively, her β-hCG level returned to normal. β-hCG secreting sarcomas are extremely rare, and to our knowledge, there has only been one previously reported case of a β-hCG secreting PEComa. Based on the limited literature, these tumours may have a worse prognosis. The role of β-hCG as a marker of treatment response and disease activity is unclear. Additional studies are required to further ascertain its role as a predictive and prognostic biomarker.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
