Abstract:
The aim of the study was the evaluation of endogenous lipid pneumonia-type changes developing in the vicinity of primary tumors of the lungs. The postoperative material collected from 56 patients operated for non-small cell lung cancer was examined. The coexistence of endogenous lipid pneumonia-type changes with squamous cell carcinoma and large cell carcinoma of the lung was most common. Patients with these histopathological types of carcinoma had lower percentage of metastases to the lymph nodes. Endogenous lipid pneumonia was found to accompany most frequently the tumors 3 < or = 6 cm in diameter and it was slightly more common in the vicinity of peripheral tumors.
