Unraveling enigmatic peripheral blood findings in a rare case of gamma-delta T-cell acute lymphoblastic leukemia
Bibliographic record
Abstract
Gamma-delta T-cell acute lymphoblastic leukemia (γδ T-ALL) is an uncommon and aggressive variant of T-cell leukemia characterized by the proliferation of immature T-cells expressing γδ T-cell receptors. Here, we present a case of a 16-year-old male with γδ T-ALL exhibiting complex clinical and peripheral blood findings. Histopathological examination of bone marrow further confirmed the leukemic nature of the condition, with a markedly hypercellular marrow infiltrated by abnormal lymphoid cells showing blast morphology. Immunophenotyping of these γδ-positive cells provided crucial diagnostic insights, including negativity for CD48, strong positivity for CD99, and positivity for TdT in a subset of cells, leading to the diagnosis of γδ T-ALL. Notably, cytogenetic analysis identified MLLT4(ADFN)/MLL(KMT2A) fusion and a TP53 deletion. The diagnostic process highlighted the challenges in differentiating γδ T-ALL from other T-cell neoplasms and underscored the importance of extended immunophenotyping for accurate diagnosis.

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.
