title: [A case of renal oncocytoma].
abstract: We report a case of renal oncocytoma and review 158 cases in the literature. The patient was a 75-year-old woman whose chief complaint was epigastric discomfort without any urological symptoms. The right renal tumor was incidentally discovered by ultrasonography. Its angiographic patterns such as spoke-wheel appearance and homogeneous nephrogram were "characteristic" of renal oncocytoma. We diagnosed it as oncocytoma by microscopical and ultrastructural observation.
