A "tumour trifecta:" myelolipomata arising within an adrenocortical adenoma ipsilateral to a synchronous clear cell renal cell carcinoma.
Bibliographic record
Abstract
We present an intriguing case of adrenal myelolipomata occurring within an adrenocortical adenoma in concert with an ipsilateral clear cell renal cell carcinoma. A 50-year-old female presented with dull right flank pain and hematuria. Computed tomography indicated a 2.5 cm right renal mass as well as a 5 cm right adrenal mass. Both masses were surgically resected concurrently. Histology of the renal mass was consistent with conventional clear cell renal cell carcinoma, Fuhrman grade III. There was no extra-renal extension or lymphovascular invasion. The adrenal mass was a cortical adenoma with solid and nested patterns, with discrete zones consisting of erythroid, myeloid and megakaryocytic cells intermixed with mature adipocytes. Mitoses were inconspicuous. The solid tumour component was strongly positive for vimentin, inhibin and CD56, focally positive for low-molecular-weight cytokeratin (Cam 5.2), calretinin and CD10 (chiefly in the myelolipomatous zones), and negative for chromogranin, S100, HMB-45, melan-A (A103), Mart-1, synaptophysin, SMA, CK7, CK20, ER, PR, TTF-1, CD99 and GCDFP (BRST-2). Ki67 (MIB1) staining indicated a low tumour proliferation index. Although well-described individually, a search of the English language literature suggests that this is the first such documented case of synchrony of these three lesions. We also present a relevant review of the literature pertaining to adrenal lesions. In particular, we emphasize the epidemiological, histological and immunohistochemical features that are helpful in determining the origin and malignant potential of adrenal lesions.

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.
