A tubular adenocarcinoma of the colon with solid area composed by small cells that was found by immunohistochemistry study using antibody to neuron-specific enolase (NSE) to possess neuroendocrine differentiation is related. In another areas of the tumor were visualized keratinizing squamous cells. The presence of neuro-endocrine and squamous cells features provide further evidence that neoplastic colonic cells have the capacity for multi-directional differentiation. The implications of this combination in relation to theories of tumor origin and differentiation and the prognostic significance of neuro-endocrine cells in malignant neoplasms of the gastrointestinal tract are discussed.
