Nevus comedonicus, also known as a comedo nevus, is characterized by a cluster of small bumps containing keratinous plugs resembling comedones. It tends to occur more frequently on the face and neck and may present in a linear, Blaschkoid or segmental pattern. It generally appears any time between birth and age 15 years, and is usually unilateral.
It is caused by mutations during development of the unborn baby. If nevus comedonicus occurs with eye, bone and nerve abnormalities, it is called Nevus comedonicus syndrome.
Treatment is with pore-cleansing strips, squeezing the comedones, applying tretinoin and CO2 laser. Cutting it out may be an option if the disease affects a small area.
It is rare, males and females are affected equally, and around half present at birth.
