Resolution of Discoid Lupus Alopecia With Systemic Hydroxychloroquine and Topical Pimecrolimus Combination Therapy.

Discoid lupus erythematosus (DLE) is an autoimmune skin condition that is typically part of the cutaneous manifestation of systemic lupus erythematosus (SLE). DLE is characterized by erythematous patches that can progress to depigmentation and alopecia, leading to scarring and permanent hair loss if left untreated. Herein, we present a unique case of localized DLE on the scalp in a 46-year-old female with no prior history of autoimmune disorders. The patient underwent several medication trials, including intralesional corticosteroids, topical calcineurin inhibitors, topical corticosteroids, and systemic hydroxychloroquine, with limited success in treating her discoid alopecia. Subsequently, a combination therapy of oral hydroxychloroquine and topical pimecrolimus significantly improved her scalp lesion. This case highlights the efficacy of combination therapy in managing localized DLE, providing valuable insights for future research focused on DLE alopecia management and optimizing treatment strategies for similar cases.
