Lymphoblastic Lymphoma and Chronic Myeloid leukemia are two distinct neoplasms with different pathogenesis and clinical presentation. We hereby share a challenging case of a child presenting with fever, leucocytosis, generalized 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 Chronic Myeloid leukemia on bone marrow aspirate. Study of more such cases is needed for optimal patient management.
