A CASE OF DIFFUSE ANTRAL VASCULAR ECTASIA WORSENED ACCORDING TO HEALING PROCESS OF GASTRIC ULCERLATION

Abstract

A 53-years old male was admitted complaining of hematoemesis with severe anemia. Emergency endoscopic examination revealed that a hemorrhagic gastric ulcerlation of A1 stage in angle on minor curveture and diffuse antral vascular ectasia (DAVE) in upper body to antrum respectively. When the ulcerlation healed to A2-Hl stage in 10-17 days after his admission, DAVE was enlarged individually and extended to all over the gastric mucosa. DAVE reduced both in size and in occupation on S1-S2 stage. Histologically, the numbers of cells positirely reacted by Grimerius method and by myeloperoxidase staining were significantly increased at the part of DAVE compered to the normal gastric mucosa. There are some reports concerned about the relation between anemia and DAVE, but it has not been reported about the DAVE which changed the size and the occupacy in association with the healing process of the gastric ulcerlation. This case is interesting, in terms of the pathophysiology of the DAVE.
