A rare case of nodular plaque variant of cutaneous-only Rosai–Dorfman disease: A case report
Bibliographic record
Abstract
Rosai-Dorfman disease (RDD) is a rare benign histiocytic proliferative disorder that classically involves lymph nodes. It often requires histopathological and immunohistochemical confirmation as it can often mimic malignancy on clinical examination and imaging. Treatment recommendations for this disease are widespread, with no clear universal approach. We present a 59-year-old otherwise healthy female with a rapidly growing and therapeutically challenging red-brown nodular plaque on the left cheek, which was consistent with an uncommon plaque-type variant of cutaneous RDD on histopathological evaluation. This case emphasizes the clinical variability of RDD and underscores the importance of histopathological evaluation to help clarify diagnosis, investigations and guide management for patients presenting with unusual clinical variants.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
