[Retroperitoneal xanthogranuloma: a case report].
A case of retroperitoneal xanthogranuloma is reported. A 51-year-old man was referred to our hospital for the evaluation and treatment of right flank pain and hydronephrosis. Intravenous urography (DIP) and retrograde pyelography revealed the stricture in the middle portion of the right ureter. Ureteroscopy revealed no mucosal lesions. Computed tomography revealed the paraureteric mass lesion. Partial ureterectomy, mass resection and uretero-ureterostomy were performed. Then a double J stent was left in place for 6 weeks. The stricture was due to a yellowish mass adhered to the right side of the ureter. The resected mass measured 1.0 x 2.0 x 1.0 cm. The histopathological diagnosis was xanthogranuloma. The patient is in good health without recurrence 4 months after the surgery.
