Psoriasis-associated periodontitis: a case report.

Psoriasis with oral manifestations is rarely seen. It has been reported in the past either as an oral manifestation of this skin disease or lichen planus accompanying psoriasis. Very few periodontal lesions associated with dermatologic psoriasis have been reported in the literature. This report describes a case of psoriasis in which exacerbation of the cutaneous disease was accompanied by gingival epithelial changes and periodontal bursts, together with a report on the light microscopy of biopsies from periodontal lesions.
