title: [Mesenchymal gastric tumor--not always GIST].
abstract: The correct histopathological classification of a gastric mesenchymal tumor as a schwannoma is essential because in contrast to gastrointestinal stromal tumors (GIST) it is a definitive benign neoplasm which can be sufficiently treated by in sano (R0) resection. A (partial) gastrectomy is unnecessary. A clear radiological or sonographical differentiation between a schwannoma and GIST is not possible. The histomorphological and immunohistochemical features of this tumor entity are described.
