Inflammatory nevus comedonicus in children.

More than 100 years has passed since the first report of a nevus comedonicus. The earliest reports emphasized the inflammatory aspect of the nevus comedonicus as being the most significant problem. In the past 30 years, publications have ignored the inflammatory aspect of nevus comedonicus while emphasizing a variety of associated malformations. In this review, we describe five prepubertal children with prominent and persistent inflammatory changes limited to areas within a nevus comedonicus. In our experience, inflammation can be severe and resistant to treatment. Ultimately, surgical removal of the involved skin was required in two children.
