Treatment of primary follicular mucinosis with imiquimod 5% cream.

Follicular mucinosis can develop as a primary form or associated with other benign or malignant skin conditions. We present a case of primary follicular mucinosis in which complete clinical remission was achieved after treatment with topical imiquimod 5%. Primary follicular mucinosis (PFM), also called idiopathic alopecia mucinosa, is considered a distinct entity, the clinical course of which is usually benign, but its pathogenesis remains unclear. There is no standard treatment for PFM, and a wide variety of therapies have been described. There are no previous reports of treatment of PFM with imiquimod.
