Hair Casts in Sisters
Abstract
- Hair casts are firm, yellowish white accretions ensheathing but not attached to the scalp and are freely movable up and down the affected shafts. There are two types of hair casts. The common type is found frequently in association with parakeratotic scalp disorders. The uncommon type, peripilar keratin cast is not associated with any cutaneous abnormality either in the scalp or elsewhere and it develops in young girls aged between 2 and 8 years. We report two cases of peripilar keratin casts that had developed in sisters who have had tightly tied-up their hairs for a long time.
