title: [Morphogenesis of carcinoid of the rectum].
abstract: Problems of carcinoid morphogenesis are rarely discussed. These tumours can originate directly from the elements of cryptal epithelial lining or from the ectopic endocrine cells. The observation described illustrates a possibility of origination of rectal carcinoid directly from the glandular epithelium cells by their springing-off the crypts, that resembles very closely the phenomenon of endophytia.
