Abstract
We report a rapidly recurring folliculostellate cell tumor of the adenohypophysis in a 63-year-old woman. Morphologically the tumor had the typical appearance of a spindle cell oncocytoma of the adenohypophysis. It recurred within 5 months of selective transsphenoidal resection, requiring a second transsphenoidal operation followed by radiation therapy. The spindle cell oncocytoma (SCO) of the adenohypophysis is a relatively recently described entity and a new addition to the fourth edition of the WHO Classification of Tumors of the Central Nervous System. In our case, the ultrastructural features were significantly different from those so far described in SCO, in that tumor cells formed a network of structures indistinguishable from pituitary follicles. In addition, a minority of tumor cells exhibited endocrine differentiation.

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
