摘要
Calcification in a lung tumor suggests that it is a benign tumor such as a hamartoma or a sclerosing lung cell tumor. In contrast, carcinoid, lung cancer, carcinosarcoma, and sarcoma rarely harbor calcification. Primary lung adenocarcinomas with gross calcification that is suggestive of bone formation are very rare. It is difficult to distinguish between calcification and bone formation purely on the basis of image definitive diagnosis of bone formation being difficult in the absence of a large surgical specimen. Lung cancers with bone formation are exceedingly rare: to the best of our knowledge, only 13 cases have been reported. Careful attention is needed when differentiating between benign and malignant tumors. Here, we report a case of primary lung adenocarcinoma with gross calcification that was suggestive of bone formation.
