Abstract
The diagnosis of tuberculosis in immunocompromised hosts is often difficult as the hosts have atypical tuberculosis symptoms. The current study presents a case of scrofula and pulmonary tuberculosis with acute myelocytic leukemia (AML). As the disease became aggravated, the patient presented with fever, hemophagocytosis in the bone marrow, lymphadenopathy of the supraclavicular fossa, and mediastinal and nodular shadow in the chest by computed tomography. The symptoms presented successively or were coexistent, which made differentiation between tuberculosis, lymphoma, AML infiltration or other infections challenging. The diagnosis of tuberculosis was based on clinical and radiographic observations, morphological observation of the biopsies and the positive effect of antituberculosis drugs, while Ziehl‑Neelsen stainings for acid fast bacilli were negative. The patient was treated with antituberculosis drugs, while receiving chemotherapy for AML. It is important to distinguish tuberculosis in adults with AML from other causes of fever, mediastinal masses in radiographic observations and hemophagocytosis in the bone marrow.
