Living with Hereditary leiomyomatosis and renal cell cancer

An inherited condition with smooth-muscle growths in the skin and uterus and a higher risk of kidney cancer.

Understanding Hereditary leiomyomatosis and renal cell cancer

Hereditary leiomyomatosis and renal cell cancer (HLRCC) is an inherited condition with benign smooth-muscle tumors in the skin and uterus and a raised risk of kidney cancer.

Skin growths (cutaneous leiomyomas) usually appear around the third decade of life, on the trunk, arms, and legs. They can be painful or sensitive to cold or touch. Most women develop many large uterine fibroids earlier than usual. About 10 to 16 percent of people develop kidney cancer, often diagnosed in their forties. It can start at a variety of ages.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Skin bumps or nodules (cutaneous leiomyomas)
  • Itching
  • Skin sensitive to cold or light touch
  • Uterine fibroids in women
  • Lower back pain, in kidney cancer
  • Blood in the urine, in kidney cancer

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include cancer specialists, genetic specialists, kidney specialists and skin, hair, and nail specialists.

  3. Consider genetic testing

    Changes in FH are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

  4. Connect with expert centers

    HLRCC Foundation may keep lists of experts for this condition.
