title: Inguinal nephroblastoma.
abstract: A case of an extrarenal nephroblastoma is reported which was located in the inguinal region. In the surrounding fat tissue normal ectopic glomerular and tubular structures and two more nephroblastomas were found. Therefore and because of negative clinical investigations in regarding of a renal malignant tumour the inguinal mass was thought to be the primary tumour and not a metastasis. This conclusion is important for the diagnosis and therapy.
