title: Melanoma and basal cell carcinoma in the hereditary leiomyomatosis and renal cell cancer syndrome. An expansion of the oncologic spectrum.
abstract: BACKGROUND
  Hereditary leiomyomatosis and renal cell cancer syndrome (HLRCC) is an autosomal dominant syndrome due to mutation in fumarate hydratase. Patients with HLRCC frequently develop cutaneous and uterine leiomyomata and are at risk for renal cell carcinoma. Rarely, other malignancies have been reported.
  
  
  METHODS
  We report the development of basal cell carcinoma and melanoma in two siblings with genetically-confirmed HLRCC.
  
  
  CONCLUSIONS
  It is unclear whether the development of melanoma and basal cell carcinoma in our patients is due directly to their mutations in the gene encoding fumarate hydratase, or genetic susceptibility at another unrelated locus, or whether these are incidental lesions. However this observation has implications for careful and routine skin surveillance in patients with HLRCC for lesions other than cutaneous leiomyomata.
