BACKGROUND

Malignant peripheral neuroectodermal tumors (MPNETs) are primitive neuroblastic tumors that arise, unlike neuroblastomas, outside the autonomic nervous system. A renal origin has been described in very few cases.

CASE REPORT

We report the case of a young male patient with a large MPNET of the right kidney, studied with ultrasound and computed tomography before surgical resection. The main radiologic features, the microscopic appearance and the typical immunohistochemical findings, are described and discussed.
