Loose anagen hair in hypohidrotic ectodermal dysplasia.
We report a 4 year-old boy affected with hypohidrotic ectodermal dysplasia in whom loose anagen hair syndrome (LAHS) was suspected clinically. The diagnosis was confirmed by examination of hair by optic and scanning electron microscopy. Loose anagen hairs have not been previously described in the ectodermal dysplasias. It is possible that our patient had real LAHS or an ectodermal dysplasia with loose anagen hair as an epiphenomenon.
