[Multiple hepatic cysts in rat rendered diabetic by streptozotocin and treated by islets of Langerhans grafts: the role of streptozotocin].

This study is based on the investigation by light and electron microscopy of hepatic biopsies from 14 rats rendered diabetic by streptozotocin and treated by portal embolization of islets of Langerhans. Macroscopically, voluminous projecting cysts were observed, sometimes occupying a whole lobe. By light microscopy, the cysts were lined with canalicular-type epithelium.
