Case 1 : A 61-year-old female was admitted to our hospital to evaluate a gastric polyp. Endoscopic examination showed a protruded lesion at the antrum. Endoscopic biopsy specimen showed benign findings. Endoscopic ultrasonography showed homogeneous hypoechoic mass in the second to the third layer of the gastric wall. This tumor was resected endoscopically, and diagnosed as an inflammatory fibroid polyp.
Case 2 : A 70-year-old male was admitted to our hospital to evaluate a gastric cancer and polyp. The cancer was located at the middle body of the stomach, and the polyp was located at the antrum. He had the cancer and polyp resected by surgery, and it was diagnosed as an early gastric cancer and IFP.
Most gastric IFP were located within the antrum (72%) , and most were smaller than 2cm in size (69%) . IFP was demonstrated as a hypoechoic tumor in the third layer of the gastric wall by EUS. Histologically, it was characteristic in the IFP that inflammatory cells containing eosinophils proliferated in the gastric deeper lamina propria mucosae and submucosa in IFP. Reports described eighteen cases of IFP that coexisted with gastric cancer. But there was no relationship between the IFP and the cancer.
