Clear cell “Sugar” tumor of the lung (CCSTL) is an atypical and mostly benign peripheral primary pulmonary tumor of Perivascular Epitheloid Cell Tumors (PEComas) family. We presented a case of CCSTL of a 59-year-old woman with a well-defined, lobulated, solitary pulmonary nodule of soft tissue density located in the right lower lobe which is persistently enhancing to 120 Hounsefield Unit (HU) in the venous phase. The patient underwent a right lower lobectomy for both the curative and the diagnostic purpose. The pathological examinations and immunohistochemical studies proved the case as a benign clear cell tumor. With only a limited number of cases reported, clinicopathological aspects and radiological characteristics of this tumor are not proposed systematically. In contrast enhancement CT imaging, the persistently up sloping enhancement characteristic of nodule like in this case might be helpful to add in separating CCSTL from other lung neoplasms.
