title: [A case of retroperitoneal serous cyst resected by laparoscopic surgery].
abstract: A 40-year-old woman was referred to our hospital because of pain extending from the left lateral abdomen to the left inferior limb. The abdominal computed tomography (CT) revealed an 8x7x12 cm retroperitoneal serous cystic mass. The serum carcinoembryogenic antigen (CEA) level was slightly elevated to 2.7 ng/ml. Therefore, we suspected it to be malignant, and we performed laparoscopic resection carefully. The retroperitoneal cyst was not adherent to the surrounding tissues and was easily dissected and removed under laparoscopy. Carbohydrale antigen (CA)19-9, CA125 and CEA levels in the fluid were elevated, but a cytology of the fluid was negative and no malignant sign was seen in the cyst wall. To our knowledge, this is the second reported case of retroperitoneal serous cyst resected by laparoscopic surgery in the Japanese literature.
