ABSTRACT
Gastric schwannoma, a rare mesenchymal tumor originating from the schwann cells of peripheral nerves, rarely occurs in the gastrointestinal tract. It accounts for only 0.2% of all gastric tumors and 2~6% of gastric mesenchymal tumors. Gastric schwannoma is observed as a subepithelial tumor on endoscopy; it is covered with normal mucosa, rendering its preoperative differential diagnosis difficult. An asymptomatic 43-year-old woman visited our hospital after a 7-cm ulcerofungating mass was detected in the lesser curvature of the gastric body on gastroscopy. Abdominal CT revealed multiple enlarged lymph nodes, and ¹⁸F-fluorodeoxyglucose (FDG) PET demonstrated a subtle uptake of FDG, suggestive of advanced gastric cancer. After three failed attempts of endoscopic biopsy, the patient underwent total gastrectomy with lymphadenectomy and was subsequently diagnosed with gastric schwannoma. Herein, we report this case with a literature review.
