[ACUTE MYELOID LEUKEMIA COMPLICATED BY DISSEMINATED TUBERCULOSIS AT DIAGNOSIS].

Abstract

A 58-year-old man was admitted to our hospital because of fever and night sweating. Laboratory examinations showed pancytopenia on admission. Examination of bone marrow smear specimens revealed many myeloblasts, thus the diagnosis of acute myeloid leukemia (AML) was made. In contrast, many central necrotic epithelioid granulomas were found in clot specimens prepared from the same bone marrow sample. Computed tomography showed small lymphadenopathies and hepatosplenomegaly. Mycobacterium tuberculosis was isolated only from the urine culture. These findings of the bone marrow and the urine culture led to the diagnosis of disseminated tuberculosis. Therefore, these results mentioned above led to the diagnosis of AML complicated with disseminated tuberculosis. After disseminated tuberculosis treatment with anti-tuberculosis drugs, induction chemotherapy for AML helped the patient to achieve complete remission (CR). During treatment and CR, he showed a paradoxical reaction with lymph node enlargement without worsening of disseminated tuberculosis. This is a rare case of AML complicated by disseminated tuberculosis.
