Localized Extramedullary Plasmacytoma: A Report of Two Cases
Bibliographic record
Abstract
Extramedullary plasmacytoma (EMP) is a rare form of plasma cell neoplasm that originates from B lymphocytes. It accounts for only 4% of all plasma cell disorders. We present two cases of EMP that were diagnosed in two different locations. The first case is a 55-year-old presented with epistaxis and sinusoidal polyps. Histologic examination disclosed plasmacytoma. The second case is a 69-year-old patient presented with upper airway obstruction caused by laryngeal mass and histologic examination revealed plasmacytoma of the larynx. Our cases are unique in their presentation and anatomic locations. To our knowledge, sinusoidal and laryngeal occurrences of the disease are only reported in a handful of cases. Both cases were treated mainly with radiotherapy. The postoperative phase was uneventful. J Med Cases. 2018;9(11):371-374 doi: https://doi.org/10.14740/jmc3179

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.
