AIMS: To clarify a clinical entity of @entity1412 of the stomach compared with generalised @entity344 . METHODS: The clinicopathological features of @entity1412 dominantly involving the stomach at initial presentation were reviewed in 12 @entity1 (three new @entity1 and nine from the literature). These were compared with 29 cases of generalised @entity344 . RESULTS: There were three @entity1 and nine @entity1 with @entity1412 of the stomach, aged 10-63 years. Hypoproteinaemia was present in nine @entity1 , @entity417 in seven, and a family history of @entity1412 in seven. No @entity1 presented with a @entity154 . During the observation period, two @entity1 developed @entity1586 . @entity1127 invariably affected the antrum and extended to the fundus, eventually becoming more numerous, larger, and more pedunculated. Ten @entity1 required gastrectomy for associated @entity5 or uncontrolled protein losing gastropathy. Histological examinations of the resected specimens demonstrated neoplastic tissue arising from @entity1127 in four of the 12 @entity1 . Atypism in these mixed @entity1127 varied from @entity652 to well or moderately differentiated @entity420 . CONCLUSIONS: @entity1412 of the stomach has malignant potential, and may be a separate entity from generalised @entity344 .
