A 47-Year-Old Man With Rosai-Dorfman Disease
Bibliographic record
Abstract
Rosai-Dorfman is a rare and benign disease with unknown etiology, characterized by histiocytosis and emperipolesis, generally associated with lymphadenopathy. It is mainly observed in Caucasians and African children and young adults. A 47-year-old man, Caucasian, with a personal history of chronic alcoholism presented with two lymph nodes with progressive growth over a period of 6 months, one located in the pre-auricular region with 2 cm and another in the sub-mandibular region with 3 cm. Clinical examination showed two discrete, non-tender, painless and immobile nodes. Biopsy of the nodes was performed. Emperipolesis and cells expressing positive immunoreactivity for protein S-100, CD1a and CD68 were observed making the diagnosis of Rosai-Dorfman disease (RDD). RDD is a benign pathology, self-limited and no special treatment is needed in most cases. J Med Cases. 2014;5(6):347-350 doi: http://dx.doi.org/ 10.14740 /jmc1599w

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.
