“…Additionally, XGP is chiefly associated with Proteus or Escherichia coli infections; also, Pseudomonas species have been implicated [7]. XGP is associated with repeated chronic inflammations, and therefore various fistulas occur including those to the intestine are most common [8].…”

Xanthogranulomatous pyelonephritis: a case with rare adhesion to pancreas

Xanthogranulomatous pyelonephritis (XGP) is a rare benign condition with unknown aetiology and chronic infection of kidney. Commonly, most cases are related with urinary tract obstruction, nephrolithiasis, infection, diabetes, and/or immune compromise. XGP is associated with destruction of the renal parenchyma and granulomatous inflammation with foamy lipid-laden macrophages resulting from obstructive uropathy. It closely mimics a malignancy, exhibiting local tissue invasion and destruction. Adjacent organs especially duodenum as well as very rarely pancreas or spleen may be involved. Additionally, XGP is known as notorious for fistulisations, such as pyelocutaneous and ureterocutaneous fistulae, which have been reported as well described. XGP may be indistinguishable from renal cell carcinoma by radiographic and clinic consultation so it must be diagnosed based on the histopathologic examinations. Furthermore, macroscopic appearance of XGP is a mass of yellow tissue with focal haemorrhage besides necrosis and in this regard, it grossly resembles renal cell carcinoma. Here, we report the case of a 32-year-old female, preoperatively diagnosed as malignancy by clinical examination. Our further pathological evaluations revealed very rarely adhesion of XGP to pancreas tissue.

Xanthogranulomatous pyelonephritis is a rare and severe form of chronic pyelonephritis. Spontaneous pyeloduodenal fistula is an extremely rare complication of xanthogranulomatous pyelonephritis. We present a rare case of xanthogranulomatous pyelonephritis complicated by a complex pyeloduodenal and ureteromuscular fistulae with a cutaneous opening. A 57-year-old male patient presented with chronic right flank pain and cutaneous discharge at the right lower quadrant. Xanthogranulomatous pyelonephritis was suspected on preoperative computed tomographic urography owing to the presence of fat deposits and complex pyeloduodenal and ureteromuscular fistulae. Open nephrectomy and fistula closure were performed and the patient recovered uneventfully. Xanthogranulomatous pyelonephritis was confirmed pathologically.

Xanthogranulomatous pyelonephritis (XGP) is a rare chronic suppurative granulomatous infection of the kidney associated with renal obstruction and progressive renal parenchymal destruction. We present an unusual clinically occult case of extensive right XGP which presented clinically with discharging right gluteal sinus and swollen right posterolateral chest and abdominal walls extending caudally to right gluteus. Contrast enhanced computed tomography of the abdomen and pelvis revealed obstructing right renal calculi, severe hydronephrosis, renal destruction and large (20.7 × 10.2 × 14.7 cm) abscess extending caudally to right gluteus. Histopathology of the specimen was concluded as right xanthogranulomatous pyelonephritis. This case demonstrates how distant an insidious XGP can infiltrate. It also emphasizes the need to have a broad range of differential diagnoses including XGP when presented with a case of gluteal abscess and sinus. Contrast enhanced computed tomography plays a key role in evaluating the cause, extent and complications of XGP and is also useful in pretreatment planning.
