@entity1 @entity706 @entity6595 @entity5 @entity1893
Between 1970 and 1978 467 @entity1893 were newly registered by the St. Gallen-Appenzell @entity5 registry. Among these 23 (4.9%) were primary @entity6595 . Among the necropsy material between 1970 and 1978 23 @entity1 (15.6%) were observed with secondary gastric involvement among 147 generalised @entity1893 . Among the 23 @entity1 whose @entity706 were investigated by use of gastric resection specimens 10 were in clinical stage IE at the time of operation, the other 13 were in stage IIE. Macroscopically there was an uncharacteristic picture of these @entity5 which were frequently localised in the antrum and ulcerated in most cases. Histologically 19 cases had diffusely growing malignancy. Four @entity5 showed nodular or follicular structures. Histiocytic and immunoblastic (n = 14 and 13, respectively) forms were the most frequently occurring @entity706 . The diagnosis of @entity706 in biopsy material could only be verified in 4 out of 12 @entity1 investigated preoperatively by gastroscopy. Histological typing of the @entity706 was not possible in most cases. When there is a suspicion of @entity706 macroparticle biopsies should be performed.
