Hereditary leiomyomatosis and renal cell cancer syndrome: a family affair.

Abstract

A 49-year-old woman with cutaneous and uterine leiomyomas, flank pain and a family history of hereditary leiomyomatosis and renal cell cancer (HLRCC) syndrome sought genetic testing. She was found to harbour a fumarate hydratase (FH) genetic mutation and a previously undetected renal tumour. The patient underwent radical nephrectomy, and remains well at follow-up. HLRCC syndrome is a rare autosomal dominant disease, with patients at increased risk for cutaneous leiomyomas, early-onset uterine leiomyomas and aggressive renal carcinoma. Although the syndrome may manifest life-threatening complications, outcomes may be improved by preventative family screening and surveillance, compelling early diagnosis.
