“…The narrow appendiceal lumen may be occluded by the tumor early during the course and predisposes it to inflammation and perforation [ 7 , 11 , 28 ]. Other possible manifestations included a palpable abdominal mass, ascites, carcinomatosis and peritonitis resulting from a perforated appendix, and a variety of nonspecific symptoms [ 16 ]. Rarely, SSA of the appendix was shown to lead to an intussusception of the appendix [ 10 , 12 ].…”

Case Reports in Surgery

Introduction. Serrated adenomas of the appendix are rare and usually found during appendectomy or autopsies. The preoperative diagnosis of these tumors is uncommon. This report describes a case of a sessile serrated adenoma located in the appendix diagnosed by a screening colonoscopy and successfully treated by laparoscopic removal. Presentation of Case. An 86-year-old woman underwent colonoscopy to investigate the cause of her diarrhea, weight loss, and anemia. During the colonoscopy, an expansive and vegetating mass of 1.5 cm in diameter was identified, protruding through the appendicular ostium with slightly lateral growth to the cecum. The patient was referred for laparoscopic surgical resection due to the location of the lesion, which did not allow its removal by colonoscopy. She underwent wedge removal of the cecum without complications and was discharged on the 4th postoperative day. Histopathological examination showed the presence of a sessile serrated adenoma with an intramucosal adenocarcinoma. The patient is currently well one year after surgery, without endoscopic signs of relapse. Conclusion. Despite serrated adenomas being a possibility rarely described in appendix it should be recognized and properly treated because it is presenting a higher risk of cancer.

“…Any neoplasm greater than 2 cm involving the base of the appendix or mesoappendix should undergo full or limited right hemicolectomy for optimal outcome. If the patient presents electively, routine tumour markers including CEA, CT scanning and colonoscopy should be performed [6]. In the emergency setting this may be inappropriate, but should there be any doubt in the diagnosis, a baseline CT scan can usually be obtained prior to surgery.…”

An Unusual Case of Appendiceal Adenocarcinoma Presenting with Rectal Bleeding and Haematuria

Adenocarcinoma of the appendix is rare, usually being diagnosed intraoperatively when performing appendicectomy or at subsequent histological examination. Here we report a case with acute abdominal pain, rectal bleeding with haematuria being the presenting symptoms. Subsequent computerised tomography demonstrated a complex mass involving the ileum, right colon, sigmoid colon and bladder with inflammatory bowel disease being the most likely cause. At laparotomy a right hemicolectomy, sigmoid colectomy and partial cystectomy was performed with pathological specimens confirming an appendiceal adenocarcinoma as the primary source of the abdominal mass fistulating into adjacent structures. We conclude that although appendiceal tumours are rare – usually diagnosed at appendicectomy, they should be considered in the diagnosis of complex abdominal masses involving small bowel, large bowel and adjacent pelvic structures.
