IntroductionNephroblastoma is one of the most common solid tumours in children. The occurrence of extrarenal nephroblastoma is exceedingly rare. What can be defined as extrarenal Wilms’ tumor must satisfy the following criteria: histologically confirmed nephroblastoma and extrarenal location.Material and methodsCurrent data on extrarenal nephroblastoma based on a selective review of the literature.ResultsThe retroperineal location is reported to be typical in males, whereas the inguinal region is believed to predominate in females. There are no characteristic manifestations of extrarenal nephroblastoma. The symptoms depend on the location and stage upon diagnosis. US, CT and MRI are used to detect tumours in the retroperiteneal space, inguinal, sacro-coccal and scrotal area. However, extrarenal nephroblastoma does not show characteristic radiological features.ConclusionsIn absence of typical clinical presentation or conclusive imaging tests, the diagnosis is based on histology after the resection of the tumor. The recommended management of the extrarenal nephroblastoma is similar to the treatment of intrarenal nephroblastoma.

We present a rare case of metachronous bilateral congenital diaphragmatic hernia (CDH) in a newborn with additional malformations: macroglossia, pectus excavatum, and confirmed Simpson-Golabi-Behmel syndrome. We performed a successful thoracoscopic subsequent repair with a patch of the bilateral type C CDH. Despite using insufflation that should cause bilateral pneumothorax at first procedure there was no clinical signs of such a one. Contralateral CDH diagnosis was possible only on the basis of the symptoms that occurred after the first operation. After 13 months the patient is without recurrence. In selected patients, staged thoracoscopy may be a safe and feasible method of bilateral CDH treatment.
