The cytological features of gastric-type adenocarcinoma (GAS). a GAS cells display monolayer or honeycomb sheet. The columnar or polygonal tumor cells show pale, foamy, and vacuolated cytoplasm with well-defined cytoplasmic borders. b An abundant lacy is present at the periphery of these sheets and the polarity is lost within clusters. c The tumor cells are round to oval in shape. Occasional nucleoli can be seen (Papanicolaou staining, 400×)
