UNIQUE APPEARANCE OF ADENOCARCINOMA OF THE ESOPHAGOGASTRIC JUNCTION ASSOCIATED WITH XANTHOMA

Abstract

A 73-year-old male with colon cancer was referred to our hospital, and gastrointestinal endoscopy for preoperative screening revealed a lesion of around 15mm at the esophagogastric junction with a highly protruding appearance. Xanthoma was diagnosed, and follow-up examination every three to six months showed no evidence of malignancy.
Magnifying endoscopy with narrow band imaging was performed at three-year follow-up, and showed malignant findings of xanthoma using the vessel-surface (VS) classification system. Adenocarcinoma was histologically diagnosed.
Magnifying endoscopy with narrow band imaging is useful for observation of gastric xanthoma with atypical appearance and the possibility of malignant formation.
