Abstract
Alopecia areata is an autoimmune disease resulting in non-scarring hair loss. Alopecia areata can progress to become alopecia totalis (loss of hair from the entire scalp) or alopecia universalis (loss of hair form the entire body), with the progression estimated to range from 7% to 30%. There are no universally proven therapies that both induce and sustain remission, and furthermore, the course of alopecia areata tends to be unpredictable, with ~80% of patients achieving spontaneous remission within 1 year. We herein present the case of a 61-year-old female who presented with a 20-year history of alopecia universalis, and biopsy confirmed widespread granuloma annulare. Hydroxychloroquine was initiated to treat her granuloma annulare, with subsequent significant hair regrowth on her scalp, eyebrows, eyelashes, and arms. A review of the literature is presented showing that hydroxychloroquine has variable success in treatment of alopecia areata, alopecia totalis, and alopecia universalis.
