“…Cut surfaces are typically homogeneous and glistening without evidence of hemorrhage, necrosis, cavitation, or calcification. Histologically, tumor cells are typical large cells with clear abundant cytoplasm and neither atypia nor mitoses, consistent with the usual behavior of a benign tumor (17). In the present case, the tumor cells showed typical morphologic features of clear cell sugar tumor with few mitoses in 50 HPF and no necrosis.…”

“…From a review of the literature, we found that certain clinicopathologic features, such as a diameter greater than 2.5 cm, the presence of symptoms, and extensive necrosis or abundant mitoses, visible under an optical microscope, are associated with more aggressive behavior (17, 18, 21). Using only cytologic study such as fine needle aspiration or biopsy, it is difficult to know these clinicopathological features of the lesion.…”

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.

“…The tumor sizes ranged from 1 mm [29] to 12 cm [10]. In our literature review, we found that certain clinicopathologic features such as a diameter >2.5 cm, the presence of symptoms, and extensive necrosis or abundant mitoses visible under an optical microscope were associated with more aggressive behavior [13,17,21,27]. Our results showed that the tumor size was most closely correlated with patients’ symptoms and tumor contour: significant statistical differences were found between the ≥2.2 cm group and the <2.2 cm group.…”

Clear cell tumor of the lung: a case report and literature review

Clear cell tumor of the lung is a rare and benign pulmonary tumor; only sporadic cases have been reported. Here, we report the case of a 38-year-old man with recurrent cough, blood-streaked sputum and left chest pain. A chest computed tomography scan showed a round, homogeneous pulmonary mass in the left lower lobe, which exhibited intense heterogeneous enhancement in the arterial phase and homogeneous in the delay phase after injecting a contrast agent. The patient underwent a fine-needle aspiration biopsy and was diagnosed as having a benign clear cell tumor of the lung. The clinical presentation and radiographic investigation of this tumor are summarized in this paper to recognize this rare disease. Interestingly, we found some differences with previously reported cases.
