Abstract
We present a case of a healthy 64-year-old man whose endoscopy showed an irregular subepithelial lesion in the gastric antrum. This lesion was covered by normal mucosa. Biopsies were taken by a bite-on-bite technique. After biopsies, the patient developed arterial bleeding, which was controlled. The anatomopathological study showed a tortuous artery in the submucosa, with a marked hyperplasia of the intima and the internal elastic lamina. These findings were consistent with a gastric arteriovenous malformation versus a Dieulafoy's lesion. This case demonstrates the risk of the bite-on-bite biopsy technique. In our country we have endoscopic ultrasound to assess these lesions, however its availability is low.
