Neurofibromatosis is a genetic condition that causes noncancerous
tumors to grow on nerves and produces abnormalities in the bones and skin. Most
cases of neurofibromatosis are mild and do not require treatment.
The most common form of neurofibromatosis causes noncancerous
tumors (neurofibromas) on or under the skin. Occasionally, noncancerous tumors
may develop in the eyes and nervous system (brain and spinal cord).
Neurofibromatosis also may cause dark spots to form on the skin that are
similar to birthmarks (called café-au-lait spots). These may vary in size and
color and may be found anywhere on the body.
There is no cure for neurofibromatosis, but treatment may relieve
symptoms. Some people choose to have large or highly visible tumors removed by surgery. Surgery to remove tumors of the spinal cord, brain, or other
nerves under the skin may be needed if the tumors are causing pain or
