Abstract
Clear cell tumors of the lung are commonly primary, clear-cell, bronchial carcinomas or metastasis of a renal cell carcinoma. Compared to this, pulmonary sugar tumor is a rare entity. A large intracellular content of glycogen and immunohistochemical procedures lead to diagnosis. The demonstration of the premelanosomal protein HMB-45 is considered as proof, but this is not airtight. We present a case of metachronic, benign, and HMB-45-negative sugar tumor of the lung after hypernephroma and give a review of the literature.
