[Cytomorphologic characteristics of poorly differentiated forms of lung cancer]

Lung cancer was diagnosed in 462 of the 738 patients with pulmonary diseases examined by x-ray surgical and radiocontrast methods. Non-differentiated lung cancer was detected in 43 of these, highly differentiated squamous-cell glandular carcinoma in 14, and poorly-differentiated squamous-cell or glandular cancer in the rest 405 (88%) patients. Differential-diagnostic cytomorphologic features of poorly-differentiated squamous-cell and glandular pulmonary carcinoma are presented.
