Abstract
The small bowel rarely develops neoplasm, and tumor of the small bowel accounts for only 1∼2% of all gastrointestinal neoplasm. Most cases of jejunal and ileal adenocarconoma are of the well or moderately differentiated type. Mucinous adenocarcinoma is diagnosed when the amount of extracellular mucin in a tumor is over 50% and its incidence in the small bowel is very low. A 49-year-old man presented with postprandial abdominal pain and vomiting for the previous 2 months. The abdominal computed tomography scan showed about a 6.5 cm-sized mass at the proximal jejunum. Single balloon enteroscopy was done preoperatively for making the diagnosis and the biopsy showed mucinous adenocarcinoma of the proximal jejunum. Under the diagnosis of primary jejunal cancer. We report here on our case for which a definite diagnosis was made before surgery by performing single balloon enteroscopy, and we review the relevant medical literature.
