[Rapidly progressing basal-cell naevi (author's transl)].

Basal-cell epitheliomas are of primary importance when discussing a case of multiple naevi. Two factors have to be considered to explain therapeutic failures: --Firstly, the very active local malignancy of these basal-cell epitheliomas; --Secondly, the long delay in applying drastic treatment such as wide excision and immediate repair, and the danger arising from divergent therapy because of lack of a common decision between the various specialists concerned: dermatologist, ophthalmologist, radiotherapist, and plastic or maxillofacial surgeon.
