Fig. 2From: Clinicopathological significance of primitive phenotypes in early gastric cancer with differentiated histologyHistological morphology of differentiated early gastric cancer with primitive phenotype. A Most of these cases (25/28) have no characteristic morphology, and cancer cells exhibit moderate to marked dysplasia. B A few cases (3/28) were characterized by cancer cells with clear cytoplasm, which was morphologically similar to primitive gut epithelium. C PAS staining displayed red particles in cancer cells with clear cytoplasm. D The red particles in clear cells disappeared when treated with diastase (DPAS staining), demonstrating glycogen deposition in these clear cellsBack to article page
