Abstract
Papillary renal cell carcinoma (PRCC) can display extensive areas of solid and non-papillary architecture and extensive areas with oncocytic cytoplasm. Eleven oncocytic renal cell neoplasms (ORCN) with histopathological features posing a diagnostic problem between renal cell carcinoma (RCC) with oncocytic features and renal oncocytoma (RO) were identified. The neoplasms were well circumscribed or encapsulated tumors with solid and diffuse growth pattern. Very occasional papillae were seen in four and tumoral necrosis in two of 11. Six ORCN displayed a CD117+/progesterone receptor (PR)+ immunophenotype (feature shared by RO) and five tumors displayed a CD117-/PR- immunophenotype (feature shared by RCC). The CD117-/PR- ORCN also displayed alpha-methylacyl-coenzyme A racemase and RCC antigen reactivity as well as varying reactivity for cytokeratin 7, vimentin and CD10 (features of oncocytic PRCC). These five cases had tumor sizes ranging from 1 to 6 cm. Two patients in the latter group developed progression of the disease with metastases. In conclusion, oncocytic PRCC with solid architecture is a rare type of RCC. The carcinoma often poses differential diagnostic problems with RO and has similar immunohistochemical properties to the common type of PRCC. Cytogenetic and molecular studies have not been performed yet for this variant of RCC.

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
