Breast metastasis of gastric signet-ring cell carcinoma

Abstract: Metastatic breast involvement from extra-mammary neoplasms is unusual with a low incidence of 0.5% to 1.2% in clinical practice, 2.7% in cytological series, and 1.7% to 6.6% in autopsy series of all breast malignancies. Nearly 500 cases have been reported in small series and case reports. Gastric carcinoma rarely metastasizes to the breast. There are only 38 cases reported in PubMed. In this study, we present a case report of a 49-year-old woman who was diagnosed with right breast metastasis from a gastric carcinoma and undertake a literature review to pay attention to the diagnosis, treatment, and the prognosis of the disease.

Key words: Breast metastasis; Gastric signet-ring cell carcinoma; Extra-mammary neoplasm

Chinese Summary  <21> 胃印戒细胞癌转移至乳腺病例分析

概要:乳腺外来源的转移性乳腺癌在所有乳腺癌中所占比例较低,约为0.5%~1.2%,胃印戒细胞癌转移至乳腺更为罕见。本文报道了一例由胃印戒细胞癌转移至乳腺的女性患者,结合相关文献回顾,探讨并总结转移性乳腺癌与原发性乳腺癌在发病机制、临床表现、影像学特点及病理组织和免疫组化中的不同点。本报道旨在提示临床医师在乳腺肿瘤的诊断中,应详细结合患者病史,考虑到乳腺外转移可能,结合病理结果及免疫组化等手段以明确诊断,早期开展后续治疗。此外,随着循环肿瘤细胞和DNA技术的不断发展,对转移性乳腺癌机制的研究更加深入,可能会为此类疾病提供更好的治疗方案。

关键词组:转移性乳腺癌;胃印戒细胞癌;乳腺外转移
