Oral lesions in psoriatic patients

Psoriasis is a chronic, recurrent, inflammatory disease of the skin. The occurence of psoriatic lesions in oral mucous membranes is a subject of controversy, and some investigators have stated that such lesions do not occur at all. In the present investigation 100 psoriatic patients were examined for the presence of oral lesions. No patient exhibited oral lesions of psoriasis; however, there was a relatively high incidence of angular cheilosis (11 per cent), fissured tongue (6 per cent), and benign migratory glossitis (5 per cent). The possibility that benign migratory glossitis is an oral manifestation of psoriasis is discussed.
