Laparoscopic Resection of a Rare Large Spindle Cell Tumor of the Stomach – Schwannoma

Abstract

Aim: To present a rare case report of a large schwannoma stomach that was adherent to the transverse colon and pancreas and was safely and effectively resected by a laparoscopic approach. Presentation of Case: A 52 years old lady presented with a large gastric mass which was initially suspected as GIST and was resected laparoscopically but final Histopathology and Immunohistochemistry results were suggestive of Schwannoma. Discussion: Gastrointestinal tract is rarely involved by schwannoma, with the stomach being the most common site. It arises from the nerve sheath of Auerbach’s or Meissner’s plexus and is observed as a submucosal tumor by endoscopy.Its accurate diagnosis is difficult to establish by preoperative CECT or endoscopy. The final diagnosis can be made only from the Histopathology and Immunohistochemistry of resected specimen. Conclusion: Laparoscopic resection of large gastric schwannomas is feasible and safe.
