概要

From 1977 to 1991, 35 pulmonary hamartomas were resected at the National Cancer Center Hospital. Hamartoma alone was present in 30. One patient also had a thymic cyst, two had lung cancer and two had metastatic tumors.<BR>Preoperatively, we found cartilage tissue by needle biopsy or exfoliative cytodiagnosis in five patients. The operative procedure was enucleation or partial resection in 78%, so postoperative complications were fewer than after operations for lung cancer.<BR>We suggest that surgery is indicated for those pulmonary hamartomas which are difficult to diagnose, which cause clinical symptoms, and which tend to enlarge also if there are associated lesions or if the patient requests surgery.
