Review Case Reports[A case of idiopathic aneurysm of the inferior vena cava].
Congenital aneurysms of the inferior vena cava (IVC) are very rare, and to our knowledge, only 4 cases have been previously reported. We describe the fifth case of fusiform aneurysm and briefly review the literature. ⋯ CT, MRI, and DSA examinations revealed an aneurysmal dilatation of the IVC measuring 51x50x38 mm inferior to the right atrium, and the diagnosis of fusiform aneurysm of the IVC was made. The newer imaging techniques of CT, MRI, and DSA have facilitated the diagnosis of this abnormality.

Case Reports[A case of bronchial actinomycosis associated with bronchoscopically removed broncholith].
A 57-year-old woman with bronchial actinomycosis associated with broncholith is presented. She had suffered from fever and productive cough for 7 years. Her chest roentgenograms showed atelectasis of the middle lobe and calcification in the middle lobe bronchus. ⋯ After treatment with antibiotics, the broncholith became movable, and it was removed bronchoscopically. Its shape was like a molding of the right middle lobe bronchus. We speculate that the growth of this broncholith partially resulted from chronic inflammation associated with actinomycelial infection.

Case Reports[A case of hypersensitivity pneumonitis due to isocyanate exposure showing progression even two months after removal of the antigen].
A 68-year-old male developed dry cough and exertional dyspnea after handling paint spray containing isocyanates (TDI, MDI) for three months. Initially, the symptoms fluctuated according to whether he was at work or not. He was admitted to our hospital on February 7, 1990, because of progressive worsening of symptoms. ⋯ One week administration of prednisolone caused dramatic improvement of his symptoms, chest X-ray findings, and laboratory data. His clinical course and response to prednisolone therapy indicated that long-term steroid administration could not be avoided. The prolonged symptoms and the necessity for long-term steroid therapy are discussed.

[Immunohistochemical analysis of CA19-9, SLX, and CA125 in adenoid cystic carcinoma of trachea and bronchus].
We examined the usefulness of 3 carbohydrate antigens, CA19-9, CA125, and SLX, as tumor markers in adenoid cystic carcinoma of the trachea and bronchus, immunohistochemically and clinically. CA19-9 and SLX were detected immunohistochemically in normal tracheal and bronchial glands, but CA125 was not detected. ⋯ In a case of bronchial adenoid cystic carcinoma in whom pretreatment serum CA19-9 showed a very high level, this marker changed in parallel with the clinical course. These results suggest the possibility that CA19-9 and SLX could be used as useful markers in patients with tracheal and bronchial adenoid cystic carcinoma.

Case Reports[A case of hypersensitivity pneumonitis in which serum specific antibodies for three species of isocyanate molecules were demonstrated].
A 64-year-old male was admitted to our hospital with complaints of the development of high fever, cough and dyspnea 5-6 hours after painting automobiles. His chest X-ray film showed interstitial shadows in both lungs. Pulmonary function test demonstrated reduction of diffusion capacity; and blood gas analysis demonstrated hypoxemia and an increase in alveolar-arterial oxygen tension difference. ⋯ The results were as follows: skin tests were positive for TDI-HSA and MDI-HSA; lymphocyte-stimulation tests on peripheral blood were positive for TDI-HSA; precipitation reaction was negative for all the isocyanates studies; enzyme-linked immunosorbent assay (ELISA) demonstrated the existence of specific IgG antibodies for TDI, MDI and HDI; inhalation challenge test by TDI-HSA was negative, but environmental provocation was considered to be positive. We diagnosed his pulmonary disorder as hypersensitivity pneumonitis due to isocyanates. Type III and Type IV allergic reactions of Gell-Coombs were suggested to be involved in the pathogenesis, however, there remains the possibility that the instability of isocyanate compounds as antigen modified the results of our immunological studies.
