Gastric antral vascular ectasia · histology

GAVE is a gastric vascular abnormality that may cause iron deficiency or gastrointestinal bleeding.

Identify tissue and stain; correlate dilated vessels with the pathology report and endoscopy.

The source describes dilated capillaries within the lamina propria and fibrin thrombi; this image is a histological section.

Associations with cirrhosis, systemic sclerosis and renal failure are reported; this section does not demonstrate them.

Portal hypertensive gastropathy is a distinct entity; cirrhosis does not make these diagnoses interchangeable.

Assess iron-deficiency anaemia, melaena and transfusion requirements; document the endoscopic distribution of lesions.

Overt bleeding with faintness or instability requires urgent assessment regardless of the histological image.

A single section cannot map the disease or select haemostatic treatment; recurrence remains possible.

Link histology with endoscopy and monitor anaemia and bleeding; distinguish GAVE from portal gastropathy.
