[Breast carcinoma metastatic to meningioma: review of the literature and description of 2 new cases].
Two cases of breast carcinoma metastatic to meningioma are described in patients 69 and 62 years old respectively.


METHODS
Cases were documented by radiological, histological and immunohistochemical techniques.


RESULTS
Both meningiomas contained an invasive duct carcinoma of the breast, one of which was apocrine in nature.


CONCLUSIONS
It is suggested that metastasis to meningioma is not so rare as it appears from the literature.
