alopecia mucinosa

Cicatricial alopecias that predominantly involve lymphocytic inflammation include lichen planopilaris, frontal fibrosing alopecia, chronic cutaneous lupus erythematosus, central centrifugal alopecia, pseudopelade (Brocq), alopecia mucinosa, and keratosis follicularis spinulosa decalvans.

Alopecia mucinosa (also known as "Follicular mucinosis," "Mucinosis follicularis,", "Pinkus' follicular mucinosis," and "Pinkus' follicular mucinosis-benign primary form") generally presents, but not exclusively, as erythematous plaques or flat patches without hair primarily on the scalp and face.
