title: [Pulmonary Nocardia otitidis-caviarum infection in a patient with Cushing's disease].
abstract: While Nocardial infections are being diagnosed with increasing frequency, infection with Nocardia otitidiscaviarum remains relatively uncommon. We report a case of pulmonary Nocardia otitidis-caviarum infection in a 35-year-old man with Cushing's disease. This work describes the first case of nocardiosis in Japan caused by Nocardia otitidis-caviarum in Cushing's disease. The patient was admitted to our department because of edema. A diagnosis of Cushing's disease was made on the basis of elevated serum levels of cortisol and adrenocorticotropic hormone (ACTH) and pituitary adenoma was found in a cranial CT scan. One month after admission, chest radiographs showed a large bilateral mass on the lung fields. Nocardia otitidis-caviarum was isolated from the sputum. The patient responded poorly to intravenous PAPM/BP, but later improved after treatment with trimethoprim-sulfamethoxazole, but he died of heart failure and respiratory failure after the initiation of this therapy. This case demonstrated that nocardiosis must be considered in differential diagnosis as an opportunistic infection.
