To examine whether paediatric acute T-cell lymphoblastic leukaemia (T-ALL) and lymphoblastic T-cell lymphoma (T-LBL) represent distinct biological entities or variants of a single malignancy.
Narrative review of clinical, immunophenotypic, cytogenetic, and molecular studies comparing paediatric T-ALL and T-LBL.
Evaluation of diagnostic thresholds, specifically World Health Organization criteria based on bone marrow blast infiltration levels.
Paediatric T-ALL and T-LBL share major morphological, clinical, and immunophenotypic characteristics, which currently leads to arbitrary classification based solely on the degree of bone marrow involvement.
Subtle cytogenetic, immunophenotypic, and molecular distinctions indicate that T-ALL and T-LBL possess unique biological properties rather than existing strictly as identical diseases.

Implication

Review highlights molecular and cytogenetic distinctions between T-ALL and T-LBL in children, suggesting these malignancies may represent biologically distinct entities rather than a single disease.
