Many moles and birthmarks on the skin are completely benign, and pose no threat to the person on whom they appear, even if they are unsightly.
Most birthmarks are benign, but some may have a malignant potential, and some may indicate systemic disease. Café au lait spots are evenly tan flat spots on the trunk and may be in the armpit area also. They can indicate internal problems. Many skin changes can be associated with internal disease, such as losing the lateral third of your eyebrow being associated with thyroid disease.
To be safe, moles exhibiting any of the following warning signs should be examined by a physician immediately:
- Larger than six millimeters
- Itches or bleeds
- Rapidly changes in color, size or shape
- Has multiple colors
- Is located where it can't be easily monitored, such as on the scalp
Depending on their depth, location and color, as well as the patient's skin type, age and other factors, treatment for benign but unattractive birthmarks is surgical excision.
