Collagenous gastritis is an extremely rare pathology of the stomach. It is seen in children and adults.
General
Clinical
children:[3]
- Dyspepsia or anemia.
- Chronic.
Adults:[2]
- Loose stools.
- Associated with celiac sprue or collagenous colitis.
Gross
- Discoloured depression - focal.[1] (???)
Microscopic
Features:
- Band of eosinophilic material (collagen) expands superficial lamina propria.[1]
- Band of collagen must be as thick as RBC diameter.
DDx:
