Familial erythromelanosis follicularis faciei et colli--an autosomal recessive mode of inheritance.

Two cases of erythromelanosis follicularis faciei et colli in one family, affecting a brother and sister are described. In these cases erythromelanosis follicularis faciei et colli, a process of unknown aetiology, seems to have a clear hereditary component--autosomal recessive mode of inheritance--a feature which, as far as we know, has not been reported in the literature.
