[Problems of bullous lesions in E.N.T. Based upon two cases (author's transl)].

The authors report two cases of bullous rashes with an ENT onset: 1. a benign mucosal pemphigoid; 2. a pemphigus vulgaris. On the basis of these cases, they indicate the need to consider the possibility of bullous lesions in the presence of any persistent erosion of the nasal or bucopharyngeal mucosa, the diagnosis of which should be dominated by the identification of a possible pemphigus, the prognostic and therapeutic consequences of which remain serious. The clinical onset may be confined for a long period to the E.N.T. musoca. It may present with dysphagia and pain, or sometimes by simple epistaxis. The commonest diagnostic errors are aphthous ulcers and candidiasis which may, in the case of the latter, be associated with bullous lesions. They also report the possible problems which may result from endoscopic manoeuvres in the case of pemphigus. Any persistent erosion of the mucosae in the E.N.T. area should be evaluated by diagnostic cytology which would offer positive identification of pemphigus.
