title: [Increased CA19-9 level in serum and bronchoalveolar lavage fluid from a patient with pulmonary tuberculosis].
abstract: A 66-year-old woman was admitted to the hospital because of general malaise and loss of appetite. Laboratory examination revealed an abnormally high level of CA19-9 in serum and a chest roentgenogram revealed soft reticular shadows in the right mid-lung field. An extensive examination revealed no malignant disease. Bronchoalveolar lavage fluid obtained from the right B5 contained an abnormally high level of CA19-9. Immunochemical staining for CA19-9 was positive in the epithelial cells of respiratory bronchioles. The level of CA19-9 decreased during anti-tuberculosis therapy. This case suggests that the CA19-9 level can reflect the activity of pulmonary tuberculosis.
