Fallopian tube cancer metastatic to the breast.

The breast is an infrequent site of metastatic disease from a primary genital tract malignancy. A case of fallopian tube carcinoma metastasizing to the breast is presented. A solitary metastasis must be distinguished from the primary breast cancer as the treatment and prognosis are quite different. The pathologic diagnosis of metastatic carcinoma to the breast may be difficult if the tumor is poorly differentiated type.
