[A new case of basal cell naevomatosis (author's transl)]

The authors, in the light of a new case of naevomatosis, review the description of the disease, emphasising its symptoms and signs, and inheritance, drawing attention to the need for surveillance of such patients in view of the risk of malignant change in the naevi. The other signs of the disease must be sought following the discovery of multiple epidermal cysts of the maxilla and mandible.
