胃腺癌(肉眼)


胃肿瘤不常见,图示胃腺癌。在美国,大多数胃癌发现时已是晚期,此时肿瘤已经浸润和(或)转移。所有的胃溃疡和胃部肿块必须检,因为仅从外观上不可能判断良恶性。相反,实际上所有的十二指肠溃疡都是良性的。
Gastric neoplasia is not uncommon. Here is a gastric adenocarcinoma. In the U.S., most gastric cancers are discovered at a late stage when the neoplasm has invaded and/or metastasized. ALL gastric ulcers and ALL gastric masses must be biopsied, because it is not possible to tell from gross appearance alone which are benign and which are malignant. In contrast, virtually all duodenal peptic ulcers are benign.
