RESUMO
Xanthogranulomatous pyelonephritis (XGP) is a rare, chronic inflammatory lesion of the kidney associated with both chronic infection and obstruction. Most common in middle-aged females, it is important to recognize in children because it may be confused with childhood renal malignancies particularly Wilms' tumor. We report a case of a 1-year old male with antenatally detected and postnatally confirmed hydronephrosis. Further investigation revealed a left incomplete duplex collecting system with obstructing lower pole stones, pelvicaliectasis and widespread foci of calcification. He underwent a left nephroureterectomy with the pathological report noting XGP.

A seven centimeter supra-renal mass was discovered in a 62-year old patient who presented with gross hematuria and a superficial bladder tumor. The supra-renal mass was resected laparoscopically and the final pathology revealed a benign schwannoma. The epidemiology, diagnostic features and treatment options for this rare peripheral nerve sheath tumor are reviewed.
