Haemophagocytosis encompasses phagocytosis of erythrocytes, leukocytes, platelets and their precursors by macrophages in bone marrow and other tissues. Haemophagocytic lymphohistiocytosis (HLH) usually presents with high fever, pancytopenia, splenomegaly, lymphadenopathy, haemophagocytosis in bone marrow, liver, lymphnodes or CSF. We report coagulase negative Staphylococcus induced HLH in a 16 year old boy presenting with high grade fever, lymphadenopathy, hepatosplenomegaly, pancytopenia with neutropenic sepsis in the department of Medicine, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh on 28th November 2016. He responded to high dose dexamethasone and management of neutropenic sepsis. This might give a guidance in the management of haemophagocytic syndrome at the earliest time to prevent morbidity and mortality.
