Haemophagocytic lymphohistiocytosis (HLH) secondary to miliary tuberculosis.

HLH is a rare, life-threatening, hematologic disorder resulting from prolonged and excessive activation of antigen presenting cells (macrophages, histiocytes) and CD8+ T cells. It is characterized by fever, pancytopenia,splenomegaly and haemophagocytosis in bone marrow,liver or lymph node. This hyperinflammatory condition is often triggered by a variety of agents or events, mostly genetic or infectious. HLH secondary to TB, have 100 % mortality in absence of anti-tubercular treatment .Since it mimics other disorders, its timely diagnosis remains a challenge. We report a case of hemophagocytic syndrome associated with disseminated tuberculosis in an immunocompetent man managed with anti-tubercular treatment and corticosteroid as immune modulator.
