[Congenital hypotrichosis and milia with spontaneous regression during adolescence or Oley syndrome: a variant of Bazex-Dupré-Christol syndrome]. / Hypotrichose congénitale et grains de milium régressifs à l'adolescence ou syndrome de Oley : variante du syndrome de Bazex, Dupré et Christol.

BACKGROUND: We report a family presenting the syndrome initially described by Oley characterized by congenital profus milia and hypotrichosis that regress during adolescence. CASE REPORT: A female infant with severe congenital hypotrichosis had profus milia involving the entire face. The remainder of the physical examination was normal. The mother had normal skin and hair but indicated she had had the same signs as a child. The patient's condition regressed from the age of 10 to 15 years but she has undergone several surgical resections for basocellular carcinoma since the age of 20. The maternal grandfather had spontaneously regressive typical follicular atrophodermia involving the back and the hands and also had several milium grains and several basocellular carcinomas. He had never presented hypotrichosis. DISCUSSION: Oley syndrome is defined as an association of congenital hypotrichosis and milia spontaneously regressive during adolescence. The symptoms presented by our patient and her mother are similar to this genodermatosis. Concomitant hypotrichosis, milia, basocellular carcinomas and follicular atrophodermia define the Bazex-Dupré-Christol syndrome. The grandfather's condition would be closer to this syndrome than Oley syndrome despite the spontaneous regression of certain anomalies during adolescence. This family study would suggest that the Bazex-Dupré-Christol syndrome and the Oley syndrome are two variants of the same condition.
