Vaginal yolk sac (endodermal sinus) tumors in infancy presenting persistent vaginal bleeding
Bibliographic record
Abstract
Vaginal yolk sac (endodermal sinus) tumors were diagnosed in two girls (ages 12 and 46 months). In both, the only manifestation was persistent vaginal bleeding. Pelvic ultrasonography, computed tomography, and magnetic resonance imaging revealed solitary vaginal masses (diameter, 5 and 2 cm, respectively). Serum alpha-fetoprotein was highly elevated in one patient and normal in the other. Biopsy was performed in the first patient, and a tumor excision, in the second. Combination chemotherapy with cisplatin, etoposide, and bleomycin or carboplatin was administered to the first patient, and shortly thereafter, the tumor size decreased by more than half; serum alpha-fetoprotein was normalized after four chemotherapy cycles. After chemotherapy, magnetic resonance imaging revealed a small residual lesion, however the second biopsy revealed no viable tumor cells. In the second patient, no visible tumor was observed after chemotherapy by vaginoscopy. Both patients are well at 19 and 14 months after diagnosis, respectively.

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.
