[A case of primary pulmonary paraganglioma]

A case of primary paraganglioma of the lung in a 48-year-old woman is presented. She was found to have a coin lesion in lower lobe on routine radiography. Results of bronchoscopic examination were negative, and exploratory right thoracotomy was performed. At operation, non-invasive encapsulated tumor found in posterior basal segment of the right lower lobe was enucleated. Histological analysis of the resected tumor proved to be compatible with pulmonary paraganglioma. Pulmonary paraganglioma is said extreme rare, and so only 21 cases were previously reported in the literature including this case.
