Follicular Mucinosis: Report of a Pediatric Case

Follicular mucinosis is a rare skin disorder in pediatrics, characterized by inflammatory reactions and abnormal mucin deposits in hair follicles and sebaceous glands, often presenting as facial papules or erythematous plaques with spot baldness. The etiology was unknown, and it sometimes associated with T-cell cutaneous lymphoma, specifically mycosis fungoides. This report detailed a case of a 15-year-old male with asymptomatic dermatosis in the left supraciliary region, showing gradual progression and comedon-like lesions. Histopathology confirmed mucin deposits, and the condition typically followed a self-limiting and benign course. However, due to its potential association with mycosis fungoides, medium to long-term monitoring with periodic biopsies was essential.
