Abstract

Follicular mucinosis (FM), also known as alopecia mucinosa, is a rare inflammatory disorder that characteristically presents as follicular papules or infiltrated plaques with prominent follicular openings associated with alopecia. Histologically, the disorder is characterized by mucin deposition in the follicular epithelium and sebaceous glands. FM was classified in two distinct entities: a primary or idiopathic form, usually presents in children and young adults with a benign course, and a secondary form in elderly associated other benign and malignant diseases. Among the malignant diseases, the main association is with mycosis fungoides. Herein we describe the case of an adolescent primary follicular mucinosis with facial lesion and discuss the clinical variants, histopathological pattern, and treatment options.
