title: A case of migrated thoracolithiasis.
abstract: A 66-year-old man was referred for evaluation of a "pulmonary nodule" found on a routine chest radiograph. Computed tomography detected a subpleural nodule of 13 mm in diameter between the upper and lower lobes of the right thoracic cavity. Follow-up chest radiograph and computed tomography after 9 months revealed migration and rotation along the right major fissure. Suspecting a pleural tumor, video-assisted thoracic surgery was performed, and a glossy white nodule of 13 x 11 mm in diameter was removed with forceps. Histopathologically, the nodule consisted of adipose and fatty necrotic tissue surrounded by hyalinized fibrous tissue. The diagnosis was thoracolithiasis.
