Follicular mucinosis (FM)/alopecia mucinosa is not commonly seen in children. There are a limited number of case reports, and its prognosis and long-term outcome are unpredictable. We describe a case of FM in a 3-year-old child, which was confirmed on histopathology. The lesion resolved with topical pimecrolimus cream and targeted phototherapy with an excimer lamp and has not recurred.
