title: A clinical study of 32 patients with oral discoid lupus erythematosus.
abstract: Thirty-two patients (26 females, six males) with discoid lupus erythematosus of the oral mucosa have been studied. Patients with signs of dissemination were classified according to accepted criteria. Four patients had systemic lupus erythematosus as well as oral discoid lesions. Twenty-one patients had discoid skin lesions. Eleven patients had oral discoid lesions without involvement of the skin. The time of onset of the oral discoid lesions rnaged from 6 to 75 years with a mean of 41 years. The mean druation of the oral lesions was 4.2 years. Symptoms from the oral discoid lesions were present in 75% of the patients. The clinical appearance varied and some lesions were difficult to differentiate from oral leukoplakia or from the lesions seen in oral lichen planus. The oral discoid lesions were most often seen on the buccal mucosa, the gingiva, labial mucosa and vermilion border. The oral lesions were infected by yeasts in more than half of thepatients.
