Abstract
Lymphoblastic lymphoma and chronic myeloid leukaemia (CML) are two distinct neoplasms with different pathogenesis and clinical presentation. We hereby share a challenging case of a child presenting with fever, leucocytosis, generalised lymphadenopathy and massive splenomegaly. He was diagnosed as having novel association of concurrent T-lymphoblastic lymphoma diagnosed on cervical lymph node biopsy with BCR-ABL negative CML on bone marrow aspirate. The study of more such cases is needed for optimal patient management.
