Morbihan Syndrome is an uncommon condition characterized by the slow appearance of erythema and solid edema on the upper portion of the face. The disease is considered an end-stage complication of rosacea's recurrent episodes of vascular dilation and inflammation or a complication of acne vulgaris. The disease is often insidious to diagnose and challenging to treat. We report a paradigmatic case of unilateral Morbihan Syndrome induced by use of fullface CPAP masks for OSAS in a patient with rosacea. OSAS could play a role in the development of rosacea symptoms. Our aim is to remark the importance of a careful, prolonged follow-up to optimize patient's management and to improve the adherence to therapy.
