Endosonographic Findings and the Natural Course of Chronic Gastric Anisakiasis: A Single-Center Experience

Figure 1

A case of chronic gastric anisakiasis histopathologically confirmed after surgical resection. (a) Endoscopy shows a subepithelial tumor-like lesion in the greater curvature of the gastric antrum. (b) On endoscopic ultrasonography, the lesion is a heterogeneously hypoechoic lesion in the submucosal layer. Hyperechoic tubular structures are seen inside the lesion (arrow). (c) Histopathological features of the resected specimen. Ill-defined granulomatous inflammation with marked eosinophil infiltration is seen in the submucosa (hematoxylin and eosin stain, ×40). Inside the granulomatous inflammation, the degenerated anisakiasis larva is observed (boxed area, hematoxylin and eosin stain, ×400).
