title: [A Case of Mesenteric Fibromatosis after Robot-Assisted Total Gastrectomy for Gastric Cancer].
abstract: The patient underwent robot-assisted total gastrectomy for an early gastric cancer. Thirty-four months later, he was admitted to another hospital because of abdominal discomfort. Computed tomography scans showed a giant solid mass approximately 13 cm in diameter in the lower abdomen. We performed a resection of the tumor; operative findings showed a giant solid tumor, without adhesion, in the mesentery of the jejunum. The tumor did not involve other parts of the small intestine. The resected tumor had a smooth surface with an elastic hard consistency. Pathological examination revealed that the tumor was immunohistochemically positive for a-SMA and b-catenin and negative for S-100, CD34, and c-kit. The tumor was diagnosed as a mesenteric fibromatosis. The patient did not show any incidence of recurrence for five months after resection. Mesenteric fibromatosis is a very rare condition and has been reported in association with Gardner's syndrome, abdominal traumas such as surgery and injury, and with pregnancy. This report describes a case of mesenteric fibromatosis after robotassisted laparoscopic surgery.
