Core Tip
Core tip: Herein is described a rare case of gastric adenosquamous carcinoma which resulted in liver metastasis and gastric cancer-related death, even though the tumor was detected at an early cancer by periodic surveillance esophagogastroduodenoscopy after gastric endoscopic submucosal dissection. Early gastric adenosquamous carcinoma is extremely rare and its clinical behavior is not well known. The present study is very significant in that it underscores the distinct possibility of gastric adenosquamous carcinoma being very aggressive and fatal even when detected at an early cancer.
