Successful Treatment of Recalcitrant Primary Follicular Mucinosis with Indomethacin and Low-dose Intralesional Interferon Alpha.

Follicular mucinosis (FM) is an epithelial reaction pattern that is characterized by the accumulation of mucinous material in the epithelial hair follicle sheath and the sebaceous glands. Although various pharmacological agents have been employed in an attempt to treat FM, effective therapeutic options have remained elusive. We experienced a recalcitrant form of primary FM that we successfully treated with indomethacin and low-dose intralesional interferon alpha (IFN alpha), respectively. To the best of our knowledge, the primary type of FM that responded to indomethacin and low-dose IFN alpha, respectively, in a single case has not been reported in the English medical literature.
