“…The tumor has been usually presented as an isolated and asymptomatic pulmonary nodule on chest radiogram ( 3 ). The sugar tumor may occur in any lobe and is mainly located under the pleura with no communication with bronchi ( 4 , 5 ). Equally often affecting both sexes, the tumor occurs in various age groups, but is most often seen in the elderly ( 6 ).…”

Clear cell tumor of the lung is a rare and very unusual benign pulmonary tumor. As clear cell tumor of the lung contains abundant cytoplasmic glycogen, this tumor is called "sugar tumor". We report a case of sugar tumor in a 64-yr-old man presenting as a round pulmonary nodule. On dynamic computed tomography (CT) scans, the solitary pulmonary nodule showed early wash-in enhancement with an early washout pattern like a lung malignancy. The patient underwent wedge resection for the tumor. Pathologic examination, including immunohistochemical studies, revealed that the nodule was a benign clear cell tumor, so-called "sugar tumor". Because only a small number of cases have been reported previously, clinical aspects, radiological characteristics on dynamic contrast-enhanced CT, and differential diagnosis of the tumor are not well established. Herein we present a clear cell tumor of the lung and discuss the clinical, radiological, and pathological features of the tumor.

“…CT usually demonstrates a round, peripheral, parenchymal nodule without calcification or cavitation. 5 The tumor is benign and surgical resection without adjuvant therapy is curative. 2,5 The differential diagnosis of a mass in the lung of a pediatric patient must include chronic infectious, inflammatory, and neoplastic diseases.…”

“…5 The tumor is benign and surgical resection without adjuvant therapy is curative. 2,5 The differential diagnosis of a mass in the lung of a pediatric patient must include chronic infectious, inflammatory, and neoplastic diseases. Although there are a number of primary lung tumors, these neoplasms are all extremely uncommon in the pediatric age group, with bronchial adenoma and carcinoid being the most frequent.…”

“…Benign clear cell tumor of the lung was first described by Liebow and Castleman in 1963l Up to now, 24 cases of this neoplasm have been reported in the English and Japanese literature. [1][2][3][4][5][6][7][8][9][10][11][12] Histologically, tumor cells show large clear cytoplasm around thin-walled blood vessels in a sinusoidlike pattern. The tumor has been commonly referred to as sugar tumor, because the tumor cells contain abundant glycogen which is stainable with periodic acid-Schiff but becomes negative after diastase digestion.…”

Benign clear cell tumor of the lung is extremely rare, and its histogenesis is still in dispute. We experienced a case of this neoplasm in the lung of a 28‐year‐old man, and carried out a study using both light and electron microscopy and immunohistochemistry. Histologically, the tumor was composed of sheets of large round or polygonal cells with abundant clear cytoplasm surrounded by thin‐walled blood vessels. Electron microscopy showed granules (180 nm in diameter) in the cytoplasm. Immunohistochemically, S‐100 protein‐positive tumor cells were seen, but other neural markers and the markers for epithelial, muscular, vascular, histiocytic and endocrine cell origins were negative. The histogenesis of this pulmonary neoplasm could not be definitively determined, but its neural cell origin remains a possibility.
