Abstract
We experienced a 46-years-old male patient with a IIc-type early gastric carcinoma, which showed remarkable change of its shape for one month. On initial endoscopic examination, 1cm sized ulceration covered with white coat developed to a slightly depressed lesion with obscure margin about for one month. We diagnosed that lesion as type-IIc like a shoal with a broken-down areolae at margin, based on stereomicroscopical examination. The marked change of shape of this lesion in a short time was supposed to be a malignant cycle of early gastric carcinoma. It was considered that the border of this lesion was made uncertain because it was located not only at the posterior wall of the ‘C’ area but also in fundic gland's area adjacent to the F-boundary line.
