A 45-year-old woman who had a gastric abnormality revealed by an endoscopy performed by a local doctor in June 1995, visited our hospital with epigastralgiain October 1995. The initial endoscopic examination only found an ulcer scar on the lesser curvature of the lower gastric body. After an inquiry of the local doctor about information of abnormalities in the stomach, the second detailed endoscopic examination revealed a IIc type early gastric carcinoma on the anterior wall of the lower gastric body which endoscopically resembled“hino-maru”type gastric telangiectasia. Pathological examination of the target biopsy specimen showed poorly differentiated adenocarcinoma.
Furthermore, the mucosal blood volume ratios (mucosal blood volume in the reddish or pale areas of the lesion/in peripheral normal areas) were calculated by means of an image analysis system. The reddish area of this lesion had similar blood volume ratio (1.37) compared with our previously reported findings of reddish type minute gastric carcinoma (1.40) , but lower than that of“hino-maru”type telangiectasia (1.91) . No significant differences were found in the mucosal blood volume ratios among the pale areas in these three types (this case : 0.87, pale type minute gastric carcinoma : 0.76,“hino-maru”type telangiectasia : 0.84) .
This report suggested that detailed endoscopic examination under condition of small amount of air supply or the calculation of the mucosal blood volume by image analysis was useful in distinguishing minute gastric carcinoma when encounter“hino-maru”type gastric telangiectasia.
