Abstract
The breast metastasis of colorectal carcinoma to the breast is rare, and radical surgery for this disease rarely improves a patient's prognosis due to the frequency of multiple metastasis. A 52-year-old man under-went low anterior resection for rectal carcinoma in March 1994 and partial hepatectomy for solitary metachronous hepatic metastasis 1 year after resection of the primary lesion. The patient underwent excision 2 more times for painless flat tumors of the right breast in May and October 1995, both tumors being histologically moderately differentiated adenocarcinoma compatible with rectal carcinoma. Since the right axillary lymphnodes became gradually swollen and no other metastatic lesions were identified, we conducted radical mastectomy (Br+Ax+Mn) in December 1995. Histological examination showed 5 further axillary lymph node metastases. The man remains disease-free 53 months after the radical mastectomy. No report has been made, to our knowledge, of such a long-surviving case following breast resection from colorectal carcinoma.
