Inflammatory fibroid polyp of the gastrointestinal tract is a rare, benign neoplasm, most frequently located in the gastric antrum. Symptoms depend on the location and the size of the lesion. Biopsies are limited for the diagnosis of inflammatory fibroid polyps and diagnosis may not be possible until resection. The authors present a case of a 55-year-old woman, presenting with an upper gastrointestinal bleeding due to a large gastric inflammatory fibroid polyp imitating a gastrointestinal stromal tumor.
