Morbihan disease (MD) is a rare entity. Its nosography is unclear and its therapeutic management is difficult. We report a new case of MD. We report a case of a 51-year-old patient consulted in our department for a one year facial edema, erythema and papules reported by him, for which the patient was treated with cyclins, local and general corticotherapy, without improvement. The clinical examination found an important edema of the front and eyelids with an erythema of the cheeks covered with a few telangiectasias. The clinical, biological and histological findings lead to a diagnosis of Morbihan disease after excluding other diseases. Due to previous therapeutic failures, the patient was put on isotretinoin and furosemide with slight improvement. The particularity of our observation lies in the rarity and especially in the therapeutic difficulties encountered during this disease.
