title: [Neurinoma with peritoneal dissemination].
abstract: A rare observation cellular neurinoma in a female of 62 is described, with a primary site of tumour in the mesenterium of the small bowel, recurrence of the disease 4 years after and peritoneal dissemination. In all nodes the tumour consisted of monomorphic cells forming twisting and palisade-like structures, few mitotic figures were seen. There were no signs of cell polymorphism. Electron microscopic examination revealed a cell structure characteristic of neurinoma' multiple complex cell processes containing single organelles, accumulations of microfilaments, collagen with a high periodicity (Luse-type bodies) as well as annular lamellar structures.
