What is the definition of Nevoid Basal Cell Carcinoma Syndrome?

Nevoid basal cell carcinoma syndrome is a group of defects passed down through families. The disorder involves the skin, nervous system, eyes, endocrine glands, urinary and reproductive systems, and bones.

It causes an unusual facial appearance and a higher risk for skin cancers and noncancerous tumors.

What are the alternative names for Nevoid Basal Cell Carcinoma Syndrome?

NBCC syndrome; Gorlin syndrome; Gorlin-Goltz syndrome; Basal cell nevus syndrome (BCNS); Basal cell cancer - nevoid basal cell carcinoma syndrome

What are the causes for Nevoid Basal Cell Carcinoma Syndrome?

Nevoid basal cell carcinoma nevus syndrome is a rare genetic condition. The main gene linked to the syndrome is known as PTCH ("patched"). A second gene, called SUFU, has also been associated with this condition.

Abnormalities in these genes are most commonly passed down through families as an autosomal dominant trait. This means you develop the syndrome if either parent passes the gene to you. It is also possible to develop this gene defect with no family history.

What are the symptoms for Nevoid Basal Cell Carcinoma Syndrome?

Main symptoms of this disorder are:

  • A type of skin cancer called basal cell carcinoma that develops around the time of puberty
  • A noncancerous tumor of the jaw, called kerotocystic odontogenic tumor that also develops during puberty

Other symptoms include:

  • Broad nose
  • Cleft palate
  • Heavy, protruding brow
  • Jaw that sticks out (in some cases)
  • Wide-set eyes
  • Pitting on palms and soles

The condition may affect the nervous system and lead to:

  • Eye problems
  • Deafness
  • Intellectual disability
  • Seizures
  • Tumors of the brain

The condition also leads to bone defects, including:

  • Curvature of the back (scoliosis)
  • Severe curvature of the back (kyphosis)
  • Abnormal ribs

What are the current treatments for Nevoid Basal Cell Carcinoma Syndrome?

It is important to get examined by a skin doctor (dermatologist) often, so that skin cancers may be treated while they are still small.

People with this disorder may also be seen and treated by other specialists, depending on which part of the body is affected. For example, a cancer specialist (oncologist) may treat tumors in the body, and an orthopedic surgeon may help treat bone problems.

What is the outlook (prognosis) for Nevoid Basal Cell Carcinoma Syndrome?

Frequent follow-up with a variety of specialist doctors is important for having a good outcome.

What are the possible complications for Nevoid Basal Cell Carcinoma Syndrome?

People with this condition may develop:

  • Blindness
  • Brain tumor
  • Deafness
  • Fractures
  • Ovarian tumors
  • Cardiac fibromas
  • Skin damage and severe scarring due to skin cancers

When should I contact a medical professional for Nevoid Basal Cell Carcinoma Syndrome?

Contact your health care provider for an appointment if:

  • You or any family members have nevoid basal cell carcinoma syndrome, especially if you are planning to have a child.
  • You have a child who has symptoms of this disorder.

How do I prevent Nevoid Basal Cell Carcinoma Syndrome?

Couples with a family history of this syndrome might consider genetic counseling before becoming pregnant.

Staying out of the sun and using sunscreen can help prevent new basal cell skin cancers.

Avoid radiation such as x-rays. People with this condition are very sensitive to radiation. Exposure to radiation can lead to skin cancers.
