Effective Treatment of Morbihan's Disease with Long-term Isotretinoin: A Report of Three Cases.

Morbihan's disease is characterized by the presence of chronic and persistent edema of the periorbital tissue, forehead, glabella, nose, and cheeks. In some cases, it is related to acne and rosacea, but its exact etiology remains unknown. A defined therapeutic approach has yet to be established for the treatment of Morbihan's disease. To date, the systemic and surgical options attempted have not been very successful and/or do not yield sustained results. Isotretinoin is a key systemic treatment used for the treatment of various skin conditions. However, there are few reports of isotretinoin being used to treat Morbihan's disease. Here, we present the details of three patients with Morbihan's disease who were successfully treated long-term with isotretinoin.
