Abstract

We report a case of gastrointestinal anisakiasis which was misinterpreted as a gastrointestinal stromal tumor until an operation and pathological report. A 44-year-old female was diagnosed as having a gastrointestinal stromal tumor on esophagogastroduodenoscopy during a routine medical examination. The esophagogastroduodenoscopy revealed a 1 cm sized submucosal tumor at the gastric mid-body. Endoscopic ultrasonography showed a low echoic tumor, with an irregular margin, in the submucosal layer. The patient underwent a wedge resection of the gastric lesion. A histological examination revealed chronic granulomatous inflammation, with abscess formation and a parasitic organism, morphologically consistent with anisakiasis.
