A 69-year-old male underwent esophagogastroscopy. A flat elevated lesion with central depression was observed on the middle esophagus. The color of the oral part was strongly red and magnifying endoscopy showed loop-shaped irregular vessels(part A). The color of the anterior part was moderately red and there were some depressed a-vascular areas with unusual surrounding vessels(part B).

 Histologically, regenerative vessels caused by erosion were observed on the surface of part A and SCC had invaded to the sm2. The vessels of part A observed with magnifying endoscopy were different from those of the part where SCC had invaded the submucosa. So, the loop-shaped vessels were considered to be regenerative vessels.

 Microscopic findings of part B revealed the exposure of BSC nests with few vessels and there were large vessels between the BSC nests. A-vascular areas of part B observed with magnifying endoscopy corresponded to the BSC nests and the unusual vessels surrounding a-vascular areas corresponded to the vessels between the BSC nests. Therefore, these findings with magnifying endoscopy were considered as the characteristic findings of BSC.
