Rosacea and Periorificial Dermatitis





Clinical Features



Highly variable degree of severity, from a few papulopustules to extreme distortion of the nose.


Lesions typically develop on the face, especially its central portion; uncommonly other sites such as the scalp and chest are involved.


Etiology is multifactorial, including vascular hyperreactivity, alterations in innate immunity, e.g. cathelicidins, and Demodex plus its commensal bacteria.
