A case of nevoid follicular mucinosis in a child

Nevoid follicular mucinosis is a new diagnosis initially described by Tadini et al1 in 2013 to represent a lesion with the Blaschkoid appearance of an epidermal nevus that exhibits follicular mucinosis (FM), or a pattern of mucin deposition within hair follicles, on histopathology. Such a presentation is quite rare, and to date, no other cases of nevoid FM have been reported. We describe herein a second case of a child with nevoid FM.
