乳腺癌比较容易转移到胃肠道,特别是胃。转移至胃的乳腺癌多为小叶癌,形态学上与原发于胃的弥漫型胃腺癌相似,如单个细胞生长模式和单个印戒细胞形态,大体上类似于胃的革囊胃。放射学、内窥镜特别是组织学检查二者很难区分。为了研究免疫组化在区分胃肠道原发性腺癌和转移性乳 Breast cancer is more easily transferred to the gastrointestinal tract, especially the stomach. Breast cancer metastasized to the stomach is mostly lobular carcinoma and is morphologically similar to diffuse gastric adenocarcinoma of the primary stomach, such as a single cell growth pattern and a single signet ring cell morphology, which is generally similar to the stomach epidermis. Radiology, endoscopy, especially histological examination is difficult to distinguish between the two. Immunohistochemistry in order to distinguish between primary gastrointestinal adenocarcinoma and metastatic milk
