Ulcerative lesions in the early gastric cancer IIc were studied from a view point of scar zone. In this paper, a difference between ulcer in IIc lesion and benign ulcer, a pattern of recurrence of ulcer in IIc lesion and correlation between ulcer and cancer were discussed.The scars in IIc lesions were mostly shallow (UI-II type) when compared with benign ulcer scars. There was also difference in location of the lesions between IIc and benign ulcer scars especially in UI-II type. Thes edifferences seemed to be due to conditions of the mucus membrane in which ulcer was produced.The ulcerative lesions in IIc were usually multiple and erosion of IIc was respnosible for frequent production of ulcer of UT-II type. Therefore, it was considered that ulcerative lesion could be produced from the lesion of cancer but that cancerous lesion could not be produced frm the lesion of ulcer.The ulcer in IIc lesions was considered to recur in the same pattern as in begin ulcer and to occur usually at different places from the previous ulcer scars.
