Hairy Nevus Syndrome
A nevus is a medical term used to describe chronic lesions on the skin that are often defined or sharply circumscribed. The most common nevi are moles and birthmarks. A nevus is often present at birth but it is also possible for the patient to acquire a nevus by other means.
Hairy nevus syndrome is a condition wherein the nevus has hair growth. This is a cutaneous condition. Males are more prone to developing this skin disorder than females although there are females who are also affected by this abnormal growth.
Like other types of nevi, hairy nevus can be congenital or acquired later in life. Congenital hairy nevus areas grow as the person grows. If the hair nevus is acquired, it will often start out as an irregular pigmentation anywhere in the body but mostly on the upper arms or torso. This pigmentation can slowly grow hair. Then, this pigmentation will slowly spread to nearby areas.
Congenital Hairy Nevus Syndrome Causes
Congenital hairy nevus is present at birth or at least had developed immediately after birth or anytime before the patient is 2 years old. About 1% of babies are affected by this skin condition. The exact reasons why this problem occurs are not yet fully understood. Still, the following are some of the possible causes:
- The most common cause for congenital hairy nevus is the proliferation of benign melanocytes on the skin, typically affecting the epidermis, dermis, or both.
- The main reason why there is a proliferation of the melanocytes could be attributed to genetics.
Hairy Nevus Removal
Hairy nevus is considered benign so that there is really no need for it to be removed in the medical sense. Still, a lot of patients would want to get rid of this abnormal growth for cosmetic purposes. To do this, the following options are possible for patients:
- The unwanted hair can be removed using conventional methods like plucking, shaving, or waxing, whichever is more convenient for the patient to do. Still, many patients prefer shaving as plucking and waxing are painful options.
- For a longer-lasting or even permanent hair removal, laser treatments will be used. Of course, this option is much more expensive than conventional methods. Still, a lot of patients prefer this over conventional methods in that the effects are permanent.
