A 62-year-old Asian man presented with a 3-month history of right iliac fossa pain which had progressively worsened over the last 3 weeks. All blood parameters were found to be unremarkable except for mildly elevated erythrocyte sedimentation rate. CT imaging demonstrated thickening of the ascending colon and caecum. Colonoscopic biopsies showed submucosal granulomas with features suggestive of schistosomiasis and parasite serology was positive for Schistosoma antibodies. He was treated with praziquantel and showed subsequent symptomatic and radiological improvement. However, he represented nearly 2 years later and underwent a right hemicolectomy for small bowel obstruction. The resected bowel showed an inflammatory caecal mass and a terminal ileal adenocarcinoma., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2020.

This is a case of a 31-year-old male patient who presented with signs and symptoms of an incarcerated inguinal hernia. The patient's preoperative imaging showed a tubular structure in the inguinal canal and given the patient's history at presentation, there was a concern for herniation of the appendix, known as an Amyand hernia. On laparoscopy, there was no evidence of appendiceal involvement and a standard open inguinal hernia was completed. On the final pathology of the hernia sac, roundworms were identified with Y-shaped lateral cords suggesting infection by Anisakis spp. On a further interview with the patient, he revealed that he had recently travelled to Alaska and had consumed raw salmon on a fishing trip. This case demonstrates the importance of a thorough social and travel history. One should also have a low threshold to broaden the differential diagnosis when medical work-up deviates from the standard course., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2020.

Amoeboma is a rare manifestation of intestinal amoebiasis. More than 90% of patients with intestinal amoebiasis have a history of diarrhoea. This report describes the case of a 60-year-old patient who presented with a right iliac fossa (RIF) mass with normal bowel habits and was eventually diagnosed with an amoeboma. In developing countries, a traditional differential diagnosis for an RIF mass is an amoeboma, but its incidence is declining. Hence this treatable condition is often overlooked in the differential diagnosis of an RIF mass. This case report emphasises that amoeboma still exists and should be considered in a patient with an RIF mass., (2014 BMJ Publishing Group Ltd.)
