A case of benign sugar (clear) cell tumor of the lung with an unusual clinical presentation and its evaluation with computed tomography are reported. A 48-year-old man presented with one episode of hemoptysis. Chest radiographs revealed a round nodule in the lower left lung lobe, and fiberoptic bronchoscopy was normal. On the computed tomography scans, the nodule showed intense post-contrast enhancement (74.7 Hounsfield units). The patient underwent a left thoracotomy, and a segmentectomy was performed. Pathologic examination showed a benign sugar cell tumor of the lung. The patient is alive and has remained free of disease for the last 2 years. To the best of our knowledge, this is the first case report of sugar cell tumor located in lung parenchyma that presented with hemoptysis and the second report of the contrast-enhanced computed tomography findings in this neoplasm.

    Solitary fibrous tumor (SFT) of the pleura and the lung is an uncommon spindle cell neoplasm arising from the visceral pleura in the majority of the cases. However there are some extrapleural sites including the lung. Current considerations were raised by a peculiar recent case: an 81-year-old...
