Gastric Schwannoma Found Incidentally 19 Years After a Horizontal Gastroplasty for Morbid Obesity

This report represents the first known case of a gastric schwannoma in a patient subsequent to a gastric stapling and partitioning procedure for morbid obesity. The submucosal tumor found in the collapsed distal portion of the stomach was merely an incidental finding and it appeared that all of the patient's ongoing symptomatology (nausea and vomiting after meals) was a reflection of the chronic obstruction that was present at the gastric partitioning staple-line. No correlation between gastric stapling and partitioning and the development of gastric schwannoma is known or is suggested in this report.
