ABSTRACT
CML is a clonal hematopoietic stem cell disorder. As per WHO classification, CML is included in Myeloproliferative disorder. Adult type - CML is rare in childhood constituting about 3% of childhood leukaemia. We have reported such a case in a 7yr old male child. Peripheral blood smear and bone marrow revealed features of chronic myeloproliferative disorder and cytogenetic analysis has proved Ph chromosome positivity. We report one such case of Philadelphia positive CML in a 7 year old male patient with chief complaints of fever on & off since 4-5 months and sense of abdominal fullness since 1 month, on examination pallor was found with mild hepatomegaly and moderate splenomegaly. The clinical differential diagnosis was malaria, storage disorder or tropical splenomegaly. Though biological behaviour and prognosis are identical to that of adult type, we are reporting this case because of its extremely uncommon incidence.
