Abstract Acute myeloid leukaemia accounts for nearly 15% of all leukaemias in children out of which only about 3% mases present with extramedullary deposits in the other sites like the orbit. Bilateral proptosis is fairly common in association with acute and chronic lymphatic leukaemia, on the other hand myelogenous leukaemia rarely give rise to proptosis. Here we present one case of 6 year old presenting as bilateral proptosis with no other manifestations of systemic malignancy at presentation. Radiological investigation, FNAC, bone marrow study and flowcytometry was done for confirmation. The purpose of reporting such a rare entity is to highlight AML as a rare but important differential diagnosis of bilateral proptosis.
