Follicular mucinosis presenting as acute dermatitis and response to dapsone

Follicular mucinosis is usually regarded as an eruption consisting of follicular papules or infiltrated plaques with prominent follicular openings associated with loss of hair. We describe a patient who presented with an acute extensive dermatitis confined to the face which was later diagnosed as follicular mucinosis. We believe that such a florid presentation has not previously been reported in the literature and serves to illustrate the difficulty in distinguishing acute follicular mucinosis from acute eczematous dermatitis, pyogenic infections and inflammatory fungal infections.
