title: Composite carcinoid carcinoma of the colon--a case report.
abstract: A composite tumour of the caecum and colon, comprising of distinct areas of classical carcinoid and of well differentiated adenocarcinoma is described. Both components were histochemically confirmed. Presence of a morphologic transition at junctional areas favour a histogenesis from bi-directional differentiation of multipotent precursor cells.
