[Endoscopic characteristics of focal hyperplasia of the gastric mucosa].

A gastroscopic examination of 58 patients with atrophic gastritis established focal hyperplasia in 3.5% of cases. Endoscopically, focal hyperplasia appeared as flat plaques, tuberosity and short folds. Early plaque-shaped cancer of the stomach was suspected in 13 cases which was histologically confirmed in I case. Different forms of atrophic gastritis were detected in 56.9% of cases of focal hyperplasia by histological examination of the material obtained by aiming gastrobiopsy. It is suggested that focal hyperplasia is an endoscopic manifestation of dysregeneratory process occurring in gastric mucosa.
