Sinonasal adenocarcinomas are uncommon tumours accounting for 3% of all malignant tumours of the head and neck. They often present with symptoms of chronic nasal obstruction and recurrent epistaxis in patients with middle age to older age group. We report a case of intestinal sinonasal adenocarcinoma in a 60-year-old male which posed a diagnostic challenge due to its rarity, uncommon radiological presentation and distinct immunophenotype. Our results demonstrate that there exists a subset of intestinal sinonasal adenocarcinoma that is CK7-/CK20+.
