Breast carcinoma metastasizing to the uterus

Metastases from mammary carcinoma represent the principal cause of exitus in 45% of subjects dead from this neoplasia. Also if they are not frequent, uterine metastases from mammary carcinoma are not very rare to find at the autopsy (2-15% as various Authors report). In this study, the Authors present 17 cases (1 bioptic and 16 autoptic cases) of uterine metastases from breast carcinoma. The histological examination confirms a more frequent involvement of the uterine corpus, with infiltration of the myometrium. When the endometrium is affected, generally the neoplasia infiltrates the stroma, preserving the glandular architecture. In one case, the uterine metastases was associated with a fibroleiomyoma. The clinical symptomatology (metrorrhagia in 3 of 17 cases) was poor because, as we have said above, generally the neoplasia infiltrates the myometrium.
