Abstract
Retroperitoneal xanthogranuloma is relatively rare. We report a case of retroperitoneal xanthogranuloma adhered to the left sciatic nerve. A 56-year-old woman was admitted to the department of gynecology in our hospital because of a tumor in the pelvic space pointed out at mass-screening for uterine cancer. With a preoperative diagnosis of peduncular uterine myoma or ovarian tumor, the patient was operated on. The tumor, 8×7×5 cm in dimension, was present in the pelvic retroperitoneal space. The tumor compressed the rectum to the right side. The tumor adhered to the sacrum and left sciatic nerve, but the dissection itself was not difficult. Total resection of the tumor was performed. Histopathologically, it was diagnosed as xanthogranuloma. The patient is alive without any signs of recurrence, as of 1 year and 5 months after the operation.
