We report a case of @entity1321 in a 73-year-old @entity1 caused by @entity3473 . The underlying cause was a @entity1066 (6   *   3.3   *   3.8  cm) extending from the superior mucosal lip of Bauhin's valve. Abdominal ultrasonography showed a pathognomonic target-like mass appearing as multiple concentric rings. CT scan confirmed the diagnosis. Because of apparent obstruction, a laparotomy with right hemicolectomy and ileocolic anastomosis was performed. @entity362 most frequently occur in the cecum and ascending colon where they represent the most common submucosal @entity361 . They typically occur in elderly @entity1 with an incidence that varies from 0.15 to 0.56  %. @entity158 , @entity548 , and obstruction are typical symptoms. When faced with an intussusception in @entity1 , reduction with air per rectum can be performed. In adults, however, malignant cell spreading and seeding is of big concern. Since approximately 20-50  % of all underlying causes are malignant, explorative surgery is favored in adults.
