Symptoms Of A Nevus Sebaceous

A nevus sebaceous is a rare birthmark that results in unusual growths on the scalp or face. It is technically a type of benign hair follicle tumor that is unlikely to cause any severe health problems. However, a nevus sebaceous can occasionally cause some complications, so it is helpful to know whether or not one is present. This type of birthmark may look fairly unobtrusive at first, so individuals often do not get diagnosed with them until they are teens or adults.
