[Chronic discoid lupus erythematosus of the mouth].

A description is given of the clinical and histologic characteristics of chronic discoid lupus erythematosus. At the same time the authors describe the results of the cytologic study carried out in keeping with the Papanicolau technique. Although no specifically indicated in the disease under consideration, the cytological method, added to the clinical study, enables a prompt presumptive diagnosis to be arrived at. However, under no circumstances does it exclude a biopsy study.
