A Case of Benign Retroperitoneal Cyst of Mullerian Type in Kidney Transplant Patient / 대한이식학회지

ABSTRACT

Retroperitoneal cysts are rare, usually asymptomatic, lesions. Mullerian cyst of the retroperitoneum is one of extremely rare disease entities and is considered to be a subtype of urogenital cysts. We present the case of a 38-year-old woman with retroperitoneal Mullerian cyst which was found during her second cadaveric kidney transplantation operation. The two-fist sized cyst was found in left retroperitoneal pelvic space extended from left common iliac artery to pre-vesical region, which compromised iliac vessels for vascular anastomosis during kidney transplantation. After complete cyst excision, the kidney transplant operation could be performed. Histologically, the cyst was lined with benign Mullerian-type epithelium. We report the pathologic findings in a rare case of benign retroperitoneal cyst of Mullerian type which was incidentally found during kidney transplant surgery.
