[Neuroendocrine tumors of pancreas (clinicomorphological, immunohistochemical and electron microscopic study)].
Neuroendocrine tumors of the pancreas were studied by histology, immunohistochemistry and electron microscopy. Tumors associated with organic hyperinsulinism showed heterogeneity in their ultrastructure, functional and proliferation activity. More than half of these tumors are multihormonal and 15% of them developed from polypotent cells which are capable for several types of differentiation.
