ABSTRACT
Breast metastases from extra-mammary malignancies are unusual. In particular, the characteristics of breast metastasis from gastric cancer are rarely reported and there is no common specific finding among the reported cases. Breast metastases from extra-mammary malignancies are often misdiagnosed as benign lesions due to the absence of characteristic finding in imaging studies; however, they also resemble inflammatory breast cancer clinically sometimes. Therefore, differential diagnosis between the primary breast cancer and the metastatic disease is considered difficult. In order to hasten the diagnosis, to avoid unnecessary mastectomy, and to determine appropriate options of treatment, it is important that physicians understand the clinicopathological and radiologic features of breast metastases and consider its possibility in patients with a history of extra-mammary malignancies. Herein, we report a case of breast metastases from gastric cancer.
