Two cases of extremely rare villous-appearing early gastric cancer adjacen to advanced gastric cancer are reported. Case 1 was a man, aged 65 years, chiefly complaining of anorexia. Gastric cancer, Borrmann type 2, 5.0×5.0 cm in size, was noted at the lesser curvature from the lower body to the antrum of the stomach, and there was a villous lesion, 2.0×2.0 cm in size, in close proximity. Case 2 was a man, aged 78 years, chiefly complaining of hematemesis. Gastric cancer, Borrmann type 4, 5.0×5.0 cm in size, was noted at posterior wall of the lower body of the stomach, and there was a villous lesion, 4.0×3.0 cm in size, in close proximity. In both cases, the advanced gastric cancers were poorly differentiated adenocarcinoma of ssγ, and the villous lesions, macroscopically and histologically analogous to villous adenoma of the large intestine, were well differentiated adenocarcinoma of m. Case 1 was diagnosed as multiple cancer because histological continuity between the two lesions was not confirmed. Case 2 was diagnosed as collision cancer because the border between the two adjacent lesions was clear on histological investigation.
