Centennial Paper. Alopecia mucinosa. Inflammatory plaques with alopecia characterized by root-sheath mucinosis. By Hermann Pinkus, M.D., Arch Dermatol 1957.

Six cases are presented which exhibit a peculiar type of follicular degeneration leading to alopecia and characterized by edema and the presence of mucin in the outer root sheath and sebaceous gland. This is accompanied by varying degrees of inflammation. The clinical lesions are sharply defined plaques which enlarge slowly and seem to be curable by relatively small doses of x-ray therapy.
