[The diagnosis of bronchiolar-alveolar cancer]

Based on clinical and x-ray studies of 123 cases of bronchioloalveolar carcinoma (BAC) verified at the clinic of lung surgery during 1964-1988, three main x-ray anatomic forms of BAC were distinguished: nodular, pneumonia-like and mixed (disseminated). Each of the forms correlates with the appropriate x-ray variants, has a specific clinical picture, requires specific differential diagnosis. Optimal methods of obtaining material with a purpose of morphological verification of the diagnosis were delineated for each of the x-ray anatomic forms of BAC.
