Atypical Gamma‐Delta‐Positive T‐Cell Lymphoproliferation With Clinical Features of Lymphomatoid Papulosis in Three Children
Bibliographic record
Abstract
ABSTRACT Primary cutaneous gamma‐delta T‐cell lymphoma has been described as an aggressive entity with a poor prognosis. However, gamma‐delta T‐cell receptor expression has been described in various types of skin lymphoproliferations. Paediatric cases of LyP are increasingly recognized, but paediatric LyP with a gamma‐delta phenotype have been rarely described. We report three paediatric patients with indolent gamma‐delta lymphoproliferation, with a relapsing‐remitting course evoking LyP. These three cases emphasize that TCR gamma‐delta expression in a lymphoproliferation is not a synonym of gamma‐delta lymphoma. Indeed, these cases raise the question of a paediatric variant of CD30‐negative lymphomatoid papulosis with histological features of atypical gamma‐delta‐positive T‐cell lymphoproliferation and underline the necessity of cautious clinico‐histological correlation when facing a gamma‐delta lymphoproliferation to avoid overtreatment.

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.
