[Coecum amoebiasis can be a rare manifestation of Entamoeba histolytica infection].

A 58-year-old Danish male was admitted to hospital with acute abdominal pain. Laparoscopy showed a normal appendix. However, a tumour in the ascending colon was found and hemicolectomy was performed. Pathological examination showed deep ulcerations with undermined edges and massive inflammation and necrosis. Periodic acid Schiff (PAS)-positive amoebae trophozoites were identified, and the patient was diagnosed with and treated for amoebiasis. The patient had not been abroad for 14 years but he worked with sewage. Patients in developed countries working with sewage should be considered at risk of developing amoebiasis.
