title: [Tsukamurella tyrosinosolvens cultured from sputum of a patient who received total gastrectomy for gastric cancer].
abstract: A 79-year old woman underwent total gastrectomy under the diagnosis of gastric cancer in Feb. 2003. In the beginning of Jan. 2005, she noticed hemosputum and was admitted to our hospital. Chest radiograph and CT disclosed bilateral upper lobe-dominant nodular opacities in the subpleural areas and ground-glass opacities in right S6. Transbronchial lung biopsy was performed, but no useful information for the diagnosis was obtained. Ziehl-Neelsen stain was negative for the smear of the sputum at admission, but weakly stained acid-fast bacilli were grown in the MGIT culture. By the analysis of mycolic acid and menaquinone of the cell membrane, the bacilli were identified as Tsukamurella. Since she was asymptomatic and repeated sputum examination revealed negative bacilli, she has been observed at the outpatient clinic without any treatment.
