Abstract
With increasing use of positive airway pressure devices for disordered breathing during sleep, appreciation for potential associated side effects is essential. Chondrodermatitis nodularis nasi is a rare variant of chondrodermatitis nodularis chronic helicis that presents as a nonhealing erosion or ulcer on the nose and can occur in association with chronic use of positive airway pressure devices. We present a case of symptomatic chondrodermatitis nodularis nasi associated with continuous positive airway pressure use, fully responsive to treatment, and propose that this condition is highly underrecognized. Dermatology referral can assist in diagnosis, management, and exclusion of cutaneous malignancy. CITATION: Reinhart JP, Isaq NA, Peters MS, Vidal NY.
