Hereditary Hypotrichosis ( Marie Unna Type )
Abstract
- We report a family suffering from Marie Unnas hypotrichosis (8 members affected in 4 generations). At birth they had normal hairs, subsequently loss of hair on the scalp, eyebrow and eyelash. At about 3rd years, coarse twisted scalp hair regrow until puberty when progressive loss from vertex and scalp margin was noticed. On physical examination and lsboratory studies, there was no associated abnormality in the patients. The scanning electron microscopic examination of the affected hair showed cuticular peeling and twisting or angulation of hair shaft.
