A novel case of hereditary leiomyomatosis- associated renal cell carcinoma with metastasis to pituitary gland.

Hereditary leiomyomatosis and renal cell cancer (HLRCC) is a rare genetic disorder characterised by a germline mutation of the fumarate hydratase (FH) gene, in which affected individuals have a high likelihood of developing cutaneous leiomyomas, uterine leiomyomas and renal cell cancer (RCC). HLRCC-associated RCC is characterised by presentation at a younger age than the sporadic form, its aggressive nature and rapid metastatic potential. We present the case of a 50 year old woman with FH mutation, a history of early onset symptomatic uterine leiomyomas, and RCC with the first reported case of an isolated metastasis to the pituitary gland.
