[Clinical analysis of benign tumors of the lung].
Benign tumors of the lung occur in low frequency, but its differential diagnosis from malignant tumors such as lung cancer is important. This paper presents as analysis of clinical features of 26 cases operated on for benign tumor of the lung. Histologically there were 15 hamartomas, 8 sclerosing hemangiomas, 2 inflammatory pseudotumors and one clear cell tumor. The roentgenographic appearances were well defined circumscribed solitary nodules in 17 cases (65%), and lobulation and spiculation in 9. Histological diagnosis of benign tumors was not obtained in all cases preoperatively. Minimal resection procedures were performed in 22 cases (85%). No postoperative complications developed.
