Multifocal capillary hemangioma-like vascular proliferation of the kidney associated with clear cell renal cell carcinoma: a case report and review of the literature.
We report the case of a 69-year-old man who underwent a radical left nephrectomy for a renal mass. Microscopically, the features were those of a clear cell-type renal cell carcinoma associated with 2 foci of capillary hemangioma-like vascular proliferation in the adjacent renal parenchyma. The main differential diagnosis and the possible pathogenesis of this vascular lesion are discussed.
