Abstract
A 48-year-old man was admitted to the hospital because of epigastric pain. He had abdominal tenderness, and inflammatory findings were noticed on the blood test. Computed tomography and ultrasonography revealed a mass with a diameter of 8 cm in the mesentery of the small intestine and abscess formation inside the mass. We performed emergency surgery, as the pain could not be controlled. Partial excision of the small intestine including the tumor was performed. Histological examination revealed a desmoid tumor composed of spindle cells with collagen fibers. Small perforation of the small intestine into the desmoid tumor was also confirmed and the abscess formation was considered the cause of the pain.
We report a case of a mesenteric desmoid tumor of the small intestine which caused acute abdominal pain, and required emergency surgery.
