Fiberscopic biopsies of the stomach for 463 patients had various lesions were performed in duration from May, 1967 to December, 1969.
To examine the cytological characteristics of so-called ATP (atypical epithelium) of the stomach, the touch-smear specimens of each biopsied one were made and investigated.
Among these were 81 cases of gastric carcinoma, 20 cases of so-called ATP, and 309 cases of benign gastric lesions according to the histological diagnosis.
The following results were obtained as the cytological characteristics of so-called ATP of the stomach in this study.
1) small columnar cells with littleincrease of nuclear diameter.
2) increase of nucleo-cytoplasmic ratio.
3) almost normal nuclear details with hyperchromasia.
4) uniformly thick nuclear rim.
5) rare prominence of nuclerlus.
6) some sbnormality of nuclear shape.
7) anisokaryosis, anisocytosis, irregular arregular arraugement of of the cells.
8) large vacuolation of cytoplasm as indirect findings.
9) Cytological findings of so-called ATP of the stomach are lacated in the middle between malignant and benign atypical cells accordiug to the statistic results calculated with each findings given scores.
