Pituitary metastasis from renal cell carcinoma: case report and review of the literature

Pituitary metastasis(PM) from renal cell carcinoma(RCC) is rare, and is easy to be misdiagnosed. Here, we present a case of pituitary metastasis from clear-cell renal cell carcinoma(ccRCC) which was difficult to distinguish from other sellar region tumors. In addition, we systematically review the literature to find the characteristics of different tumors of the sellar region. It provides a new idea for the diagnosis of sellar region tumors in the clinic.
