Three new cases of follicular mucinosis have been described. In addition to the characteristic changes in hair follicles and sebaceous glands, all three cases showed mucinous degeneration of the dermis. In one case the staining reactions with PAS and Giemsa stains appeared to indicate that the dermal mucin differed from the follicular mucin, and contained a glycoprotein rather than acid mucopolysaccharides. Because of the high percentage of spontaneous regression, it is difficult to evaluate the response to therapy. Rapid response of one case to systemic corticosteroids suggested that this therapy had an actual effect.
