[Cutaneous manifestations of McCune-Albright syndrome: report of a case (author's transl)].

An 11-year-old boy with fibrous dysplasia of bone of the McCune-Albright syndrome type led to a search of the literature for reports of cutaneous signs other than hyperpigmented macules. We have found descriptions of patchy alopecia, verrucous nevi, soft tissue tumours and other cutaneous abnormalities associated with the McCune-Albright syndrome. Our patient presented in addition pili torti, dermal cysts and a pre-auricular appendix which are all signs not previously described in this syndrome. Our observation is in keeping with the hypothesis that there is a congenital ectodermal and mesodermal mal development to account for this polydysplasia.
