Rectal adenocarcinoma with additional neuroendocrine component is an extremely rare entity with about a little more a dozen of cases being reported in the literature. Mostly the neuroendocrine component is that of well-differentiated type (carcinoid); sometimes can be the unusual variant of neuroendocrine carcinoma capable of distant metastasis. Here we report a very rare case rectal cancer which was a diagnostic dilemma for us with the final histopathological examination revealing it to be a composite tumour of the rectum having adenocarcinoma and a more aggressive neuroendocrine carcinoma component with a solitary liver metastasis from the neuroendocrine component.
