A Case of Bullous Morphea Resistant to Methotrexate and Phototherapy Successfully Treated With Mycophenolate Mofetil

Bullous morphea is rare clinical variant of localized scleroderma characterized by the formation of bullae on sclerotic morphea plaques. Severe disease may be highly disabling and greatly impair quality of life. Current treatment strategies are based on anecdotal reports of clinical experience and include topical corticosteroids, methotrexate and phototherapy. Herein, we describe the case of a 56-year-old woman with progressive bullous sclerotic lesions who was successfully treated with mycophenolate mofetil after treatment failure with psoralen plus ultraviolet A therapy, ultraviolet A1 phototherapy, and methotrexate. Treatment with mycophenolate mofetil halted disease progression after 8 weeks. No major adverse effects were recorded in a 3-year follow-up with continuous treatment. This case suggests mycophenolate mofetil may be considered as an alternative for the treatment of resistant bullous morphea lesions.
