Follicular Mucinosis (Alopecia Mucinosa)

Three new cases of follicular mucinosis were described, showing characteristic changes in hair follicles, sebaceous glands, and mucinous degeneration of the dermis. One case indicated that dermal mucin might contain glycoprotein rather than acid mucopolysaccharides. Due to high spontaneous regression rates, evaluating therapy response is challenging, but one case responded rapidly to systemic corticosteroids, suggesting potential therapeutic efficacy.
