Definition

A rare type of epidermal nevus characterized by closely arranged, dilated, plugged follicular ostia in a honeycomb pattern. The plugged ostia contain lamellated keratinaceous material, and their appearance resembles black dots. NC may be non-pyogenic with an acne-like appearance or associated with the formation of cysts, papules, pustules, and abscesses. Most commonly it affects the face and neck area and, by exception, other anatomical regions, including genital area, palms, and soles. NC lesions might present with various patterns of distribution: unilateral, bilateral, linear, interrupted, segmental, or blaschkoid.
