Intravascular bronchiolo-alveolar tumor (IVBAT). Case report with the immunological analysis.
A case of intravascular bronchiolo-alveolar tumor, a rare lung neoplasm which is often found among women, is reported. Our ultrastructural findings and existence of factor VIII-related antigen support the hypothesis of vascular origin. The relationship between IVBAT and epithelioid hemangioendothelioma is discussed. We also examined whether immunological abnormalities existed in our patient, because tuberculin test gave negative result in many cases reported previously and our case. No specific immunological change was found except for negative tuberculin test.
