title: Neuro-endocrine tumours--their origin and classification.
abstract: The neuro-endocrine cell is an integral component of many organ systems, and it is therefore not unexpected that this cell is identified in a variety of tumours. The embryology of this cell is uncertain and the recent literature indicates the presence of more than one type of neuro-endocrine cell. The classification of neuroendocrine tumours is addressed, a working classification is proposed and attempts made to clarify the concept of neuro-endocrine neoplasia.
