[Dermatoses with localization in the mucous membranes of the mouth and lips - various recommendations].

Review of some observations in the Department of Dermatology of the Medical-Stomatological Institute of the Ministry of Health, Moscow. From 1200 patients with lichen planus, 32% had lichen only on the mouth and lips. 5 types have been distinguished: the typical type, the exsudative hyperaemic type, the erosive ulcerous type, the bullous type and the atrophic type. In 55% of the patients with lupus erythematosus, only the lips were involved. A pemphigoid-like condition of the mucous membranes is mentioned, but without skin lesions and without scar formation. 33% of 100 patients with erythema multiforme had only lesions on the mucous membranes. In Behçet-disease, circulating IgE seems to be of importance. In cheilitis exfoliativa, physical factors are of importance. In Melkersson-Rosenthal-syndrome, the active-T-lymphocytes and the lymphocytes with staphylococci antigene receptors are elevated in the peripheral blood.
