title: [A retrospective clinico-morphologic study of insulinoma].
abstract: Surgical material from 51 patients operated on for insulinoma is studied. Three histological variants of insulinoma are distinguished: adenoma-like, insular-ductal and carcinoid-like. The structure of Langerhans islands outside the tumour is described and the diagnostic criteria of insuloma-microadenoma are presented. Multiple nests of the endocrine cells are regarded either as a manifestation of the multifocal island pathology or as a marker of non-diagnosed insuloma. There is a need of distinguishing between the terms related to the nosology and histogenesis of endocrine pancreatic tumours.
