Pediatric pityriasis lichenoides and cutaneous T-cell lymphoma
Bibliographic record
Abstract
PURPOSE OF REVIEW: The purpose of this review is to educate the reader about two cutaneous lymphoproliferative diseases in childhood: pityriasis lichenoides and cutaneous T-cell lymphoma. Pityriasis lichenoides has traditionally been divided into acute and chronic subtypes. The two forms of the disease, however, are best thought of as two ends of a benign lymphoproliferative spectrum. Cutaneous T-cell lymphoma is a rare but underrecognized cutaneous malignancy in children. Early stage disease and hypopigmented presentation are characteristic of pediatric cutaneous T-cell lymphoma. The optimal investigation and treatment plans are still controversial. RECENT FINDINGS: This article will summarize recent articles on pityriasis lichenoides and pediatric cutaneous T-cell lymphoma, including recent findings from an international registry of pediatric cutaneous T-cell lymphoma. SUMMARY: After reading this review, the reader should be able to recognize the clinical presentation of pityriasis lichenoides, to understand the overlap between its acute and chronic forms, and to recognize its relationship with cutaneous T-cell lymphoma. In addition, the reader will appreciate the challenges in diagnosing and treating pediatric cutaneous T-cell lymphoma.

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.
