Carcinoma (TNM-classification see table TNM ).
Prepyloric gastric carcinoma
Prepyloric gastric carcinoma Large, nearly circumferential antral carcinoma Circumferential antral carcinoma
Prepyloric gastric cancer. The tumor shows a rodent pro- liferation in the shape of a bowl in the prepyloric antrum. Central hematin hints at an oozing hemorrhage prior to endoscopy. The traces of blood at the bottom are caused by biopsy. Peristaltic movements are com- pletly absent in this part of the stomach. Pictures of an antral carcinoma, which developed a hugetumorous cavity. Next to the ulcerations the tumor also has exophytic parts bleeding easily. The whole visible gastric section consists of tumor, there is no normal, gastric tissue. In the background a glimpse of the pylorus can be caught.
Synchronous carcinoma of the cardia and the body
Carcinoma of the corpus Carcinoma of the cardia The left picture shows a G3 carcinoma of the body, the right picture depicts a cardial papillotubular adeno carcinoma. Both tumors were well apart from eachother and developed in the same patient at the same time. The patient was treated by gastric resection.
Ulcerous carcinoma
Ulcerous carcinoma Ulcerous carcinoma These gastric ulcers turned out histologically as carcinomas. Any exophytic part is absent. This underlines the absolute rule, that from every gastric ulcer representative biopsies have to be taken.
