The study is an observational, multi-center, prospective, non-interventional and open-label data collection study assessing outcomes, treatment patterns, adverse events and costs in patients diagnosed with bullous pemphigoid. The patient enrollment period will be 1 year with a follow-up (observation period) of 1 year for each patient. Four dermatology centres in France will participate. The hypothesis to be answered by the study is that superpotent topical corticosteroid therapy is properly used to treat bullous pemphigoid in real-world life as recommended by French guidelines and whether this treatment influences the medical costs by comparison with systemic therapies (e.g. methotrexate or prednisone).
