This patient presented with anaemia.
At endoscopy the patient was found to have a large hyperplastic polyp in the stomach. This video sequence demonstrates the characteristic PIT pattern of the hyperplastic lesion using PENTAX HD+ and i-scan enhancement.
This image enhancement was used to direct YAG laser therapy to this area to prevent further blood loss.
