Gastric inflammatory fibroid polyp treated with Helicobacter pylori eradication therapy.

Gastric inflammatory fibroid polyps (IFPs) are rare benign lesions that occur in the distal stomach. We describe a 70-year-old woman with Helicobacter pylon-positive gastric IFP treated with eradication. Gastroduodenal endoscopy revealed a pyramidal-shaped, broad-based tumor with an ulcerated apex at the antrum. Helicobacter pylori was positive by both histology and tissue culture, and eradication (a proton pump inhibitor, amoxicillin, and clarithromycin) was performed. After 3 months, the tumor morphologically changed and the apex ulcer was markedly enlarged. This case suggests that H. pylori may play a role in the pathophysiology of IFPs.
