In the small intestine, anaplastic carcinoma is a rare variant with few cases reported in literature. We report a case of a 55-year-old male who presented with intussusception and lower abdominal pain. Microscopically, the tumour showed a diffuse growth pattern unlike conventional adenocarcinoma. The present case discusses the histomorphology of anaplastic carcinoma of small intestine, its immunohistochemical profile and the differential diagnosis of this rare but highly aggressive tumour.
