Multifocal CD4+ Primary Cutaneous Small/Medium Lymphoproliferative Disorder Successfully Treated With Low-Dose Oral Methotrexate: A Case Report
Bibliographic record
Abstract
Primary cutaneous CD4+ small/medium T-cell lymphoproliferative disorder (PCSM-LPD) is a rare indolent disorder often associated with a favourable prognosis. It typically presents as a solitary skin lesion, mainly in the head, neck, or upper trunk region. Multifocal PCSM-LPD is a rare entity, with no standard treatment approaches available. In this article, we present the case of a 56-year-old male patient with multifocal biopsy-proven PCSM-LPD that was treated with methotrexate orally at 10 mg/m2 body surface area weekly and successfully achieved full clinical resolution by the 10th week of therapy. A review of the literature indicates the efficacy of combination chemotherapy. However, due to the indolent nature of this disorder and the undesired side effects from combination chemotherapy, our treatment method involved oral methotrexate alone, and it was successful. Oral methotrexate is a potential therapeutic option in the management of multifocal PCSM-LPD and it warrants further investigations.

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.
