Abstract
Gastric schwannoma that originates from nerve sheath comprises about 0.2% of all gastric tumors and 4% of all benign gastric tumors. It is difficult to precisely diagnose gastric schwannoma via endoscopic biopsy or imaging studies. A 57-year-old male was referred to our hospital from a private clinic for further evaluation of a gastric tumor-mass that was diagnosed by gastroscopy. Gastroscopy and endoscopic ultrasonography showed a submucosal mass larger than 3 cm in size at the low body of the stomach. That the mass had malignant potential could not be excluded because of its size and shape. The patient underwent subtotal gastrectomy. The tumor cells showed immunoreactivity to S-100 protein. This submucosal tumor was diagnosed as a gastric schwannoma on the basis of these findings. Gastric schwannoma is known to occur more frequently in females than males. This is the first reported case of gastric schwannoma that's occurred in a Korean male patient. (Korean J Gastrointest Endosc 2007;34:210⁣213)
