Pituitary menastasis from arenal cell carcinoma prosressed after sorafenib treatment

Abstract

Pituitary metastasis from renal cell carcinoma is rare and has never been reported for renal cell carcinoma primarily treated with sorafenib. Herein, we present a case of an advanced clear-ce ll renal cell carcinoma in which pituitary metastasis progressed but extracerebral metastases showed partial response to sorafenib treatment.
