Endoscopic findings:
(1) findings seen in mild gastritis, as described by Taor et al
(2) findings seen in more severe disease
Endoscopic findings in mild to moderate gastritis:
(1) fine pink speckling, or "scarlatina" type rash
(2) superficial reddening, which gives the superficial rugae a striped appearance
(3) a fine white reticular pattern separating areas of raised red edematous mucosa resembling a "snake skin"
where:
• The reticular pattern is analogous to the mosaic patterns described by Tanoue et al and others.
Endoscopic findings in more severe gastropathy:
(1) discrete red spots similar to the cherry red spots seen in esophagus, which can become confluent and which may bleed
(2) diffuse hemorrhagic gastritis
Histopathologic features in endoscopic biopsies:
(1) normal
(2) gastritis
(3) mucosal and/or submucosal vascular ectasia involving capillaries and veins
