We appreciate the comments of Drs Matsushita and Okazaki about our brief report of gastric anisakiasis.1 We also recognize the usefulness of the serologic test for the diagnosis of subclinical anisakiasis.2 In this brief report, we did not examine the serologic test because we diagnosed the gastric anisakiasis that resembled early gastric cancer by direct observation of Anisakis larvae. We also agree with their comment that the serologic test is important for the diagnosis of the histologically benign ulcerative lesion resembling gastric cancer. Therefore, as we described in our report, we think it is possible to conclude that the gastric anisakiasis should be considered when such an ulcerative region resembles gastric cancer without the histopathologic findings of malignancy.
