Topical immunomodulation with diphenylcyclopropenone for alopecia areata: the Lebanese experience.

Topical immunotherapy with diphenylcyclopropenone (DPCP) is a treatment that can be used in patients with alopecia areata (AA) with more than 50% involvement of the scalp. The aim of this study is to assess the response of our patients with AA treated with topical immunotherapy with DPCP at the American University of Beirut-Medical Center (AUB-MC) and to characterize the favorable prognostic factors that predict response to treatment. This is a retrospective study of all patients diagnosed with AA at AUB-MC and treated with topical immunotherapy with DPCP over a period of 10 years.
