Introduction and importance: We report an extremely rare case of appendiceal neuroma, presented as an incarcerated Amyand’s hernia. Case presentation: A 55-year-old male presented in the emergency department due to a persistent right inguinal painful swelling. Clinical examination revealed a 5cm x 3cm firm and irreducible right groin mass. Under the diagnosis of an incarcerated right inguinal hernia, an emergency operation was performed. Intraoperatively, a 5cm x 3cm firm mass originating from the distal part of the appendix was found in the hernia sac. The operation was completed with an appendectomy and a modified Bassini hernia repair. Histological examination revealed appendiceal neuroma, and no further surgical intervention was needed. Discussion: Appendiceal neuroma is a benign stromal tumor whose diagnosis is typically made by histopathologic study. Though not clear, pathogenesis is believed to stem from the proliferation of neuroendocrine cells due to frequent inflammatory attacks. It is usually confused with the presentation of appendicitis, and the diagnosis is confirmed after the appendectomy. Amyand’s hernia, on the other hand, is an inguinal hernia whose content is either normal or diseased appendix vermiformis. In the literature, very limited case reports of Amyand’s hernia containing a carcinoid tumor, goblet cell carcinoid tumor, mucinous cystadenoma, adenocarcinoma, and villous adenoma are listed. However, we found no single reported case of Amyand’s hernia containing appendiceal neuromas in our search of English literature using Google Scholar and PubMed search engines. Conclusion: Amyand’s hernia containing appendiceal neuroma is an extremely rare entity. We found no case report in the accessible literature. Histopathological evaluation is important to differentiate appendiceal neuroma from malignant tumors of the appendix. An appendectomy alone with hernia repair is adequate treatment.

“…Majority of patients with Amyand's hernia are urgently operated for a preliminary diagnosis of incarcerated or strangulated hernia, and Amyand's hernia is an incidental finding during surgery 1 , 10 . Therefore, the role of radiological tools is very limited 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. Cases without an urgent condition may be diagnosed with US or CT 1, 2, 3.…”

“…The most commonly encountered pathological features are normal appendix vermiformis, acute appendicitis, perforated appendicitis, and periappendicular abscess. However, a very limited number of cases of an appendiceal tumoral lesion inside the Amyand's hernia sac has been reported in the literature.We encountered 8 case reports while searching the English literature from the PubMed and Google Scholar databases 4, 5, 6, 7, 8, 9, 10, 11. Two cases had carcinoid tumor; two cases had goblet cell carcinoid tumor; two had mucinous cystadenoma; and one case had adenocarcinoma, and one had villous adenoma.…”

“…The treatment of an Amyand's hernia typically varies whether the appendix vermiformis in a hernia sac is complicated or not. Detection of an appendiceal tumor inside an Amyand's hernia is an extremely rare situation, and only a few cases have been reported 4, 5, 6, 7, 8, 9, 10, 11. In this study, we aimed to report a 64-year-old man who was found to have a carcinoid tumor inside an incarcerated Amyand's hernia sac.…”

Introduction Amyand's hernia is defined as the herniation of the whole or a part of appendix vermiformis into an inguinal hernia sac. Amyand's hernia is very rare, constituting about 1% of all inguinal hernia patients and 0.1% of all acute appendicitis patients. In one-quarter of Amyand's hernia patients, inflammatory changes are detected in appendix vermiformis. Detecting an appendiceal tumor in an Amyand's hernia sac is extremely rare, with only eight cases having been reported so far in the English literature. Case presentation A 64-year-old man with an appendiceal carcinoid tumor inside an incarcerated Amyand's hernia sac. As the tumor was localized to the radix of the appendix, resection was carried out with the help of a linear-cutter stapler in a way to contain a part of the cecal wall. As the pathology examination revealed a carcinoid tumor infiltrating the periappendicular fatty tissue, right hemicolectomy was performed in a second session, in compliance with the oncological principles. No metastasis was present at the 24th month. Case reports published in the English literature regarding the Amyand's hernia with an appendiceal tumor were also analyzed in this study. Conclusion Amyand's hernia containing an appendiceal tumor is an extremely rare clinical entity. Clinical manifestations mostly mimic the incarcerated hernia and thus accurate diagnosis is made incidentally during hernia surgery. The basic oncological principles apply for the approach to tumors inside a hernia sac.

Primary malignancies of the appendix are rare. Of these, less than 5% are goblet cell carcinoid (GCC) tumours. The majority of GCC present with findings of acute appendicitis or advanced peritoneal spread. We describe a rare presentation of GCC as subtle mucosal abnormality of the appendiceal orifice seen on colonoscopy performed for iron-deficiency anaemia. Biopsies were interpreted as adenocarcinoma; however, final surgical pathology confirmed GCC of the appendix with caecal involvement. The patient recovered well from surgery, anaemia resolved and follow-up did not show metastatic disease.
