Abstract
Dermatopathic lymphadenitis (also known as lipomelanotic reticulosis, or Pautrier–Woringer disease) is a rare type of benign lymphatic hyperplasia associated with a variety of exfoliative or eczematoid type inflammatory erythrodermas. The axillary and inguinal regions are most commonly affected, although occasionally it can present in the head and neck as well. On histologic examination, the affected lymph nodes contain melanin and fat-laden reticular cells. This is a case of a 10-year-old boy with a history of severe eczema, who presented with enlarged lymph nodes. F-18 FDG PET/CT imaging showed intensely FDG-avid lymph nodes in the cervical, axillary, and inguinal regions and a diagnosis of lymphoma was suggested; however, histopathology revealed dermatopathic lymphadenitis. This entity is a potential pitfall in the F-18 FDG PET/CT evaluation of lymphoma and should be considered in the differential diagnosis, especially in individuals with a history of inflammatory erythrodermas. To our knowledge, this is the first report of F-18 FDG PET/CT imaging of dermatopathic lymphadenitis mimicking 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.
