Peripheral neuroepithelioma of the kidney

Abstract

Peripheral neuroepithelioma is a rare tumor, comprising less than 1% of all soft tissue malignancies arising from the peripheral nonautonomic nervous system. Most peripheral neuroepitheliomas reported were located in the extremities, thoraco-pulmonary region, and pelvic areas, and as many as 30% of cases were associated with peripheral nerve. We report one case of peripheral neuroepithelioma arising in the kidney, mimicking renal cell carcinoma on the CT scan.
