Plasmacytoma cases with unfamiliar clinical features
Bibliographic record
Abstract
Plasmacytoma is a relatively rare form of plasma cell dyscrasias with indolent clinical features. Major localizations are in the upper airways and the region of head. Since it represents only a minority of all plasma cell neoplasms, careful histological review should be addressed to the specimens of these patients. In this paper the authors report three cases, developing plasmacytoma with uncommon clinical features. First patient had an unfamiliar localization of plasmacytoma in the cerebellopontine angle which was first meant to be malignant meningioma and later a large subcutaneous mass was detected in the gluteal region. Second patient developed plasmacytoma after a prostate adenocarcinoma as a secondary malignancy. Third patient, developed plasmacytoma and definite plasma cell myeloma with a coexistence of systemic sclerosis. Treating patients with chemo-radiotherapy, and irradiating the one with localized disease resulted in complete remission in two out of the three patients. Imaging techniques such as positron emission tomography combined with computed tomo- graphy (PET-CT) proved to be useful as tumor exploration tool, however multidisciplinary cooperation is recommended in these cases.

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.
