Follicular Mucinosis: Report of a Pediatric Case

Follicular mucinosis was a rare skin disorder characterized by an inflammatory reaction with abnormal mucin deposition in hair follicles and sebaceous glands. Its etiology was unknown, and it often presented with facial lesions such as papules or erythematous plaques, desquamation, and spot baldness. The condition required anatomopathological confirmation and was sometimes associated with cutaneous T-cell lymphoma, specifically mycosis fungoides. The document reported a case of a 15-year-old male with asymptomatic dermatosis in the left supraciliary region, showing gradual progression and specific histopathological features. The significance of the report lay in the rarity of this condition in pediatric patients and its typically self-limiting and benign nature, although long-term monitoring was essential due to potential associations with mycosis fungoides.
