An unusual case of a relationship between rosacea and dental foci.

Rosacea is a chronic disorder affecting the facial convexities, characterized by frequent flushing, persistent erythema, and telangiectases. During episodes of inflammation, additional features are swelling, papules, and pustules. The exact etiology of this dermatitis is unknown, and theories abound. Infectious foci, especially dental foci, seem to be rarely associated with the onset and progression of this disease. Dermatologic treatments are determined by the severity of the disease. But eradication of infectious foci, and in this case eradication of dental foci, may generate a significant improvement and may lead to a recovery.
