Abstract
ABSTRACT Beckwith-Wiedemann syndrome (BWS) is an imprinting disorder characterized by overgrowth, congenital malformation, and tumor predisposition. Children with BWS have a higher incidence of tumors, commonly intra-abdominal tumors such as Wilms tumor, hepatoblastoma, and adrenal cortical carcinoma. Here, we describe the first case of a rare hepatic malignancy of nested stromal epithelial tumor (NSET) of the liver in a child with BWS. A 22-month old girl with BWS had a new incidental liver mass. Her alpha-fetoprotein levels were normal. She underwent a liver segmentectomy. Histopathologic features combined with immunohistochemistry results (positivity for pankeratin [AE1/3], CD56, CK19, CD117, CD99 [weak membranous pattern], β-catenin, and WT1-COOH [focal]), were diagnostic of NSET of the liver. This is the first case of NSET of the liver associated with BWS. Its occurrence at such an early age is consistent with the tumor predisposition of BWS.

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 it
