Giant hyperplasiogenous polyp of the stomach simulating malignant polyp.
A surgical case of giant hyperplasiogenous polyp of the stomach with unusual radiological and pathological findings is presented. Radiological and endoscopical examinations revealed characteristic papillary (villous) features simulating either true adenoma or malignant polyp of the antrum. Complete serial sections from the resected stomach disclosed no malignant area anywhere in and out of the polyp. The pathomorphological nature and radiological characteristics of this rare lesion are discussed.
