[Intraoperative histologic verification of focal diseases of the lungs].

The article deals with the results of histological study of material of emergency biopsies and subsequent scrupulous examination of lung resectates obtained from 50 patients with focal diseases of the lungs which were not identified precisely and unverified morphologically before the operation. Inflammatory pseudotumors of two types and in different phases were revealed in 19 patients, different forms of active tuberculosis--in 9, different forms of primary carcinoma of the lungs--in 8, proliferative processes bordering on malignancy--in 5, silicosis and silicotuberculosis--in 4, and suppurative and sclerotic changes--in 4 patients. The results confirm the importance of close cooperation of the surgeon and morphologist at all stages of the diagnosis.
