Hypernephroma metastasis in the pituitary gland. A case report.

In a 59-year-old man with a hypernephroma tumour of the right kidney, a metastasis in the pituitary gland of this neoplasm was diagnosed 9 years after removal of the kidney. However, metastases were also found in the left kidney. It cannot be established whether the metastasis in the pituitary gland came form the original tumour or from the other diseased kidney. To the best knowledge, a hypernephroma metastasis to the pituitary gland has not been reported previously.
