Rare Presentation of Alopecia Universalis Congenita and Twenty-nail Dystrophy in Siblings
نویسندگان
چکیده
Congenital alopecia universalis is one of the rarest anomaly which involves skin and appendages. The inheritance pattern can be autosomal recessive, X-linked recessive, or autosomal dominant. However, the most common is autosomal recessive form and it is the most severe phenotype. Twenty-nail dystrophy refers to the condition in which all the twenty nails are affected in the form of excessive ridging and nail plate roughness leading to unsightly lustureless nails. We report a rare case of two siblings with alopecia universalis congenita with twenty-nail dystrophy. To the best of our knowledge, this case is the first case to be reported with such association in both siblings. This case reports highlights the fact that alopecia areata is an autoimmune disease with a genetic predisposition as in our case both siblings had alopecia universalis and nail dystrophy. There was no evidence of any other ectodermal dyplasia and had normal teeth and seat glands. The skin biopsy ruled out congenital atrichia and was suggestive of alopecia areata.
