Myeloid sarcoma in a child with acute myeloblastic leukaemia.

We report a rare occurrence of myeloid sarcoma in a 7 years old child with acute myeloblastic leukaemia (AML-FAB type M2). He presented with fever, generalized weakness, bilateral proptosis and left parotid swelling. CT scan revealed a mass in paranasal sinuses extending into brain and retro-orbital region. Diagnosis of AML M2 was made on bone marrow aspiration and special stains. Induction therapy for AML was given according to standard protocol. The extramedullary lesion as well as the acute leukaemia went into complete remission.
