Appendiceal cancer was strongly suspected in this case because of its unique colonoscopic, radiologic, and intraoperative presentation. Hence, laparoscopic enbloc right hemicolectomy and peritonectomy were performed. The diagnosis of periappendiceal abscess was confirmed later after the operation. Appendiceal disease is hard to differentiate because of the wide spectrum of differential diagnosis. So, when there is a strong suspicion of appendiceal cancer, laparoscopic right colectomy, which is minimally invasive and potentially curative can be the treatment of choice.
