Rosacea and Use of Continuous Positive Airway Pressure Mask for Obstructive Sleep Apnea Syndrome: Report of Five...

Rosacea is a chronic inflammatory skin disease of unknown etiology. We noticed a series of patients who were diagnosed with rosacea as well as obstructive sleep apnea syndrome (OSAS), for which they used a continuous positive airway pressure (CPAP) mask. This case series aims to give insight in the possible relationship between rosacea and the use of a CPAP mask for OSAS. We present five patients with OSAS who developed or worsened rosacea symptoms after use of a CPAP mask covering nose and mouth. Two patients showed centrofacial symptoms consistent with the shape of the CPAP mask; three patients had nasal cutaneous symptoms. It is postulated that the occlusive effect of the CPAP mask, increasing skin humidity and temperature, can induce primary symptoms in patients with an underlying sensibility for rosacea. This could have implications for choice of CPAP mask type and topical therapeutic options for rosacea.
