The document described a case of a patient with both alopecia areata (AA) and psoriasis vulgaris who experienced the Renbök phenomenon following contact immunotherapy. The Renbök phenomenon, first introduced by Happle et al., refers to the observation of normal hair growth within psoriatic lesions in patients with co-existing psoriasis and AA. The exact mechanism behind this phenomenon remained unclear. The study highlighted the potential of contact immunotherapy to induce this unique response, providing insights into the complex interactions between these two dermatological conditions.
