title: Lepromatous leprosy masquerading as disseminated tuberculosis.
abstract: A patients with disseminated leprosy is described. A 57 year old man from Cuba presented with fever and pancytopenia. Bone marrow aspirate showed numerous acid-fast bacilli and a liver biopsy specimen contained multiple granulomas. The patient was considered to have tuberculosis and was treated with isoniazid and rifampin, with initial clinical improvement, only to have the fever recur and to show deterioration in hematologic and hepatic function. Failure to grow M. tuberculosis suggested a diagnosis of leprosy which was proved by skin biopsy. How lepromatous leprosy can masquerade as disseminated tuberculosis is discussed.
