Unusual Morphologic Features of Endometrial Stromal Tumors
Bibliographic record
Abstract
Endometrial stromal tumors with typical morphology usually do not pose diagnostic problems. However, the finding of unusual morphologic features may be misleading in the final interpretation of these tumors. Herein, we described two endometrial stromal sarcomas discovered in hysterectomy specimens of women 31 and 75 years of age. Features typical of endometrial stromal neoplasia were present in both cases. Additionally, in 1 case, extensive fatty metaplasia as well as smooth and skeletal muscle metaplasia were found; and in the second case, focal bizarre nuclei, smooth muscle differentiation, and fibrous change were present. The differential diagnosis in the first case included cellular intravenous leiomyomatosis/lipoleiomyomatosis with skeletal muscle differentiation; and in the second case, a cellular smooth muscle tumor with bizarre nuclei was considered.

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.
