[Early gastric carcinoma. 20 cases. Radioclinical, endoscopic and histopathological study (author's transl)]

The authors report twenty cases of early gastric carcinoma: superficial and with limited infiltration. The histological appearances varied, related to the macroscopic type of the tumour: protuberant, ulcerated, flat. The slightest clinical symptoms justify the most careful radiological study. Protuberant types result in a filling defect. Ulcerated types have a characteristic appearance of superficial ulcer, the folds involved being nodular or widely spread. Deeper regressive ulcerations are sometimes seen in association. Flat forms after the folds of a localised area of mucosa. The differential diagnosis is difficult. It is particularly important to eliminate the possibility of a benign ulcer, polypoid gastritis, lymphoid superficial ulcer, atrophic gastritis, well healed benign ulcer. Combined radiological and endoscopic studies are essential at all stages.
