[A HEALTHY ADULT WITH DISSEMINATED NONTUBERCULOUS MYCOBACTERIAL INFECTION WITH MULTIPLE BONE LESIONS].

A 54-year-old man was admitted to our hospital because of fever, dyspnea, and low back pain. Chest computed tomography showed a 30-mm mass in the left lung and bilateral pleural fluids, multiple bone lesions, enlarged lymph nodes, and skin abscesses. Mycobacterium avium was isolated from his sputum, a pleural fluid sample, the right cervical lymph node, and a precordial skin abscess. We thus diagnosed his illness as disseminated nontuberculous mycobacterial infection (DNTM) and treated him with multiple chemotherapeutic agents. However, the disease progressed, and he ultimately died. He was not in an obvious immunocompromised state. DNTM with multiple bone lesions in a healthy adult is very rare and we therefore report this case.
