 “Hand-shaking/Crawling-type” adenocarcinoma often resembles complete-type intestinal metaplasia and exhibits characteristic branching and anastomosing glands. These lesions endoscopically show an indistinct border, and their biopsy diagnosis is often difficult due to their low-grade histology. Thus, understanding the clinicopathological features of this adenocarcinoma is essential for making an accurate diagnosis. Recently, we conducted a mutation analysis of “hand-shaking/crawling-type” adenocarcinomas and identified RHOA mutations in half of the cases. In this article, we review the histological and molecular features of “hand-shaking/crawling-type” adenocarcinoma, including recent study results.
