H. Pylori in a gastric schwannoma: a case report

Ann Transl Med. 2016 Apr;4(7):137. doi: 10.21037/atm.2016.03.55.

Abstract

Schwannomas are benign, often asymptomatic, slow-growing tumors that originate from Schwann cells of the neural sheath. Although H. Pylori has been associated with gastric adenocarcinoma, there has never been a recorded association with schwannoma formation. We present a 64-year-old woman who underwent a laparoscopic partial wedge gastrectomy for an incidentally discovered gastric mass. Histologic examination was consistent with schwannoma; however, chronic inflammation with microorganisms morphologically consistent with H. Pylori was also present. This case suggests the first recorded case of H. Pylori in an immunohistochemically confirmed gastric schwannoma.
