We aimed to study the clinicopathologic features of inflammatory fibroid polyp by histological and immunohistochemical methods. The materials used in this study consisted of 9 cases of inflammatory fibroid polyp: 4 in the stomach, 4 in the small intestine and 1 in the cecum. The results were as follows: Females were affected more frequently than males and the average age was 45 years(range:27-61). In cases of gastric lesion, the size tended to be smaller, the mass was mainly located along the greater curvature side of antrum, and confined to the submucosa. However inflammatory fibroid polyp of the small intestine was over 2.5 cm in size, located along the antemesenteric border, and involved the proper muscle layer. In addition, intussusception was accompanied by polyp in 2 cases of small intestinal lesions. Histologically inflammatory fibroid polyps of the stomach were characterized by prominent lymphocytic infiltration and occasional onion-skinning of stromal cells, whereas plasmocytic infiltration was prominent in those of the small intestine. Main component cells comprising this lesion were confirmed to be fibroblasts by immunohistochemistry which revealed strong reactivity to vimentin in the cytoplasm of slindle cells.
