[Cytologic diagnosis of stomach neoplasms]

Personal experience in the cytological diagnosis of gastric neoplasis acquired in a series of 104 patients is presented. Three false positives were detected in 29 cases of supposed malignancy and 11 false negatives in 75 patients with tumours thought to be benign. Cytology often proved the determining factor in the planning of surgery, while in some instances it also gave an indication of the histological type involved.
