A Rare Case of Collision Tumor: Coexistence of Adrenocortical Adenoma and Pheochromocytoma in the Same Adrenal Gland
Bibliographic record
Abstract
Simultaneous occurrence of both adrenocortical adenoma and pheochromocytoma in the same adrenal gland is extremely rare in the literature. We report a 38-year-old female who presented with palpitation, chest pain and tremor with a right adrenal mass consistent with adrenocortical adenoma on computed tomography. Both metanephrine and normetanephrine levels were high in the urine. The biochemical tests strongly suggested the diagnosis of pheochromocytoma. Pathological examination of the adrenalectomy specimen revealed a collision tumor composed of an adrenocortical adenoma and a pheochromocytoma. Although rare, the present case is noteworthy in highlighting the importance of conducting biochemical tests to rule out pheochromocytoma for any adrenal mass prior to surgery. doi:10.4021/jmc451w

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.
