Abstract:
Eosinophilic abscess is a rare disease of stomach that consists of many eosinophils in submucosa and muscle layers of stomach. Eosinophilic abscess is usually observed in liver after parasite infestation such as hepatic fascioliasis or in intradermal lesion of pemphigus. A 67-year-old female was admitted due to epigastric pain and indigestion. Endoscopic finding suggested early gastric cancer type IIc with the depth of invasion to mucosal layer at the lesser curvature of lower body. Histologic examination of endoscopic biopsy proved to be signet ring cell type adenocarcinoma. On endoscopic ultrasonography, the tumor was imaged as a slightly elevated mass with 15 mm in diameter. The lesion was localized from the first layer to the fourth layer which correspond to the mucosa and the proper muscle layer, The lesion consisted of low echoic and isoechoic densities. The lower echoic lesion ranging from the third layer to the fourth layer was thought to be necrotic or hemorrhagic portion within the tumor. Subtotal gasterectomy was performed. We compared the endoscopic and endosonographic features with the histologic findings of the resected stomach. Histologic examination showed signet ring cell carcinoma in mucosal layer and eosinophilic abscess in submucosal and proper muscle layer. We concluded that the endosonographic depth of invasion was overestimated because of the eosinophilic abscess.
