Psoriasis with oral manifestations.

A forty-seven year old woman had skin and oral lesions of three year's duration. The skin lesions were clinically and microscopically diagnosed as psoriasis. Oral examination revealed extensive involvement of the entire mucosa with white, elevated, circinate lesions. Biopsies of oral mucosa were interpreted as histologically similar to the characteristic dermal findings in psoriasis. Anesthetic mouth rinses afforded symptomatic relief; however, although there was definite improvement, the oral lesions have persisted.
