title: [Mesenchymal tumor of the small pelvis with hypoglycemic syndrome].
abstract: In spite of a large size, mesenchymal tumor of the small pelvis was not diagnosed clinically, and hypoglycemia was considered as a manifestation of hyperinsulinism. The tumor was identified as mesenchymal, most likely fibrosarcoma, immunohistochemically. The use of antibodies against insulin, glucagon and somatostatin showed the disturbance in the balance of cells in the hyperplastic islands of the pancreas. Multifocal hyperplasia of the islands is considered as a compensatory adaptive reaction to paraneoplastic extrapancreatic hypoglycemia.
