Breast Metastasis of Gastric Signet-Ring Cell Carcinoma:A Case Report and Literature Review

乳腺外源性转移癌较为少见,约占所有乳腺恶性肿瘤的0. 3%~2. 7%,部分来源于胃癌,其中绝大多数为胃印戒细胞癌。乳腺转移癌的影像学表现缺乏显著特异性,主要依靠病理检查与乳腺的其他肿瘤鉴别。由于缺少相关流行病学方面的数据,目前关于乳腺转移性胃癌的病因、治疗方法仍不明确。本文将收治的一名胃印戒细胞癌乳腺转移患者的诊疗经过汇报如下,并对既往报道的病例进行复习,对该类疾病的流行病学、病因学及诊治相关研究进展进行总结。

Exogenous breast metastases are rare,accounting for 0.3%-2.7% of all breast malignant tumors,partly from gastric cancer,the vast majority of which are gastric signet ring cell carcinoma.Because the imaging findings of metastatic carcinoma are lack of significant specificity,we rely on pathological examination to distinguish it from other breast tumors.The etiology and treatment of gastric cancer metastasis to the breast are still unclear due to the lack of relevant epidemiological date.We reported a case of breast metastasis of gastric signet-ring cell carcinoma in this study,and reviewed the cases in the past,summarized the research progress on the epidemiology,etiology,diagnosis and treatment of the disease.
