 Esophageal lymphangioma is extremely rare. Up to 2012, only 13 cases had been reported in Japan. They were 8 men and 6 women, aged between 32 years and 74 years. Most of the lesions were smooth, soft, and transluscent. Histologically, in 11 of 14 cases, they occupied lamina propria mucosae as well as the submucosa. We report a 43-year-old male with lymphangioma in the lower part of the esophagus, which was diagnosed after endoscopic submucosal dissection. Magnifying endoscopy with NBI revealed that the overlying mucosa became transparent in spots due to thinning of the stratified squamous epithelium. We present this case with endoscopical and pathological correlation.
