Anisakiasis is a parasitic infection caused by the consumption of raw fish containing larvae of the Anisakis species. Since the first description in 1960 of a patient suffering from this pathogen, in the Netherlands, most of the cases have been reported in Japan, where consumption of raw fish is common, but the number of cases is increasing worldwide. The first case identified in Italy dates back to 1996 and a few cases have been reported since then. In Italy the intestinal form occurs almost as frequently as the gastric form, which is far more frequent in Japan. Intestinal Anisakiasis represents a diagnostic challenge as it is clinically misdiagnosed and most of the patients require surgery due to the occurrence of complications such as bowel occlusion or perforation. Practically no cases of the intestinal form are diagnosed preoperatively. We report the first case, to our knowledge, of intestinal Anisakiasis in which surgery was avoided, due to a prompt diagnosis suspected on intestinal biopsies. A literature review of Anisakiasis cases reported in Italy is also carried out.
