Year 4niche
A 72-year-old woman with well-compensated alcoholic cirrhosis (Child-Pugh A) is referred due to persistent iron deficiency anaemia.
She denies haematemesis, melaena, or overt GI bleeding. Stool occult blood is intermittently positive. She has received several blood transfusions over the past year.
An upper endoscopy reveals no oesophageal or gastric varices.
However, the antral mucosa appears diffusely erythematous with subtle linear red streaks radiating from the pylorus. There is no active bleeding, and no ulcers are seen. Biopsies show mucosal vascular dilation and fibrohyalinosis.
