Bone marrow metastasis of prostatic adenocarcinoma with post-treatment foamy-like changes: A diagnostic pitfall
Bibliographic record
Abstract
Prostatic acinar adenocarcinoma (PAA) is the most common malignant tumour of the male genital system. Hormonal therapy and radiotherapy are widely-used treatment modalities in advanced stage disease. However, with hormonal therapy, the morphology of the neoplastic cells can be altered with a shift towards benign-appearing cells with inconspicuous nucleoli and abundant cytoplasm. When the tumour spreads to the bone marrow, these neoplastic cells can mimic foamy histiocytes, which may lead to a misdiagnosis. This becomes more challenging if a concurrent bone marrow malignancy is identified. Attention should be paid if foamy cells are detected in bone marrow, particularly if the patient has a history of PAA. To the best of our knowledge, this is the first report of simultaneous bone marrow involvement by metastatic PAA with mimicking foamy histiocytes and lymphoplasmacytic lymphoma.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
