title: Unusual manifestation of extrapulmonary tuberculosis.
abstract: Though commonly encountered, extrapulmonary tuberculosis (TB) can sometimes present with variable clinical picture intricating the diagnosis (Avasthi et al., 2010). The nonspecific symptoms include pyrexia of unknown origin, hepatosplenomegaly, lymphadenopathy, meningitis, and, rarely, variety of hematological abnormalities, namely, anemia, pancytopenia, and leukemoid reaction (Avasthi et al., 2010). When it presents with bone marrow (BM) involvement, prognosis is usually poor (Avasthi et al., 2010, Qasim et al., 2003, and Singh et al., 2001). We, hereby, report a case of extra-pulmonary TB with a six-month history of fever associated with dizziness, fatigability, and cough. During the hospital stay, the patient showed a spectrum of interesting hematological findings, including severe pancytopenia on peripheral smear, necrotizing caseating granulomas consistent with TB on bone marrow examination. The patient showed a good clinical as well as hematological response to antituberculosis treatment. This paper highlights the significance of a hematological picture in the final confirmation of TB, which may otherwise be passed off as nutritional or other unrelated causes.
