Cafe-au-lait spots are a light tan spot, the color of coffee with
milk. They may be a normal type of birthmark. The presence of
several cafe-au-lait spots larger than a quarter may occur in
neurofibromatosis (a genetic disorder that causes abnormal cell
growth of nerve tissues).
Moles are small clusters of pigmented skin cells. Nearly everyone
has moles, which usually appear after birth.
Congenital nevi (moles present at birth) have an increased risk
of becoming skin cancer (malignant melanoma). This is especially
true if the nevus covers a large area of the body (larger than a
fist). All congenital nevi should be examined. Watch for
changes in the size or color, or the appearance of sudden
ulceration, bleeding, or itching in the birthmark.
A mongolian spot (also called a mongolian blue spot) is usually
bluish or bruised-looking. It usually appears over the lower back or
buttocks, sometimes in other areas including the trunk or arms.
These are more commonly seen in darker-skinned populations and may
persist for months or years but do not become cancer or develop
other symptoms.
These skin spots are treated by our office using the Comet or Quantum SR
Laser.
