MACROSCOPICAL AND HISTOPATHOLOGICAL MULTIPLICITY OF DEPRESSED TYPE OF GASTRIC CARCINOMA-RELATIONSHIP WITH THE DEPTH OF INVASION-

Abstract

The majority of the depressed carcinoma of the stomach have the ulceration in the lesion. We sometimes observe the healing of the malignant ulceration. By the rise and fall of the ulceration in the cancerous lesion, the depressed floor showed all kinds of morphological change. According to this fact, we carried out the study of the relationship between the depth of invasion and macroscopical status with the ulceration in the cancerous lesion. The objects were 33 depressed type gastric carcinomas with the ulceration. The comparative study was carried out between macroscopical and microscopical findings. The results were as follows; 1. The cases in mucosal cancer showed the granular pattern on the depressed floor. 2. According to increasing the cancer volume below submucosal layer, macroscopical findings of the depressed floor became rough. 3. Histopathological findings of the mucosal cancer showed the stratum and sanctuary type by the status of malignant cycle.Consequently, there is a strong relationship between the healing cource of the malignant ulceration and cancer invasive volume below the submucosal layer.
