Epidermolytic hyperkeratosis
Epidermolytic hyperkeratosis Causes
The cause of this condition is traced from defects in genes for keratin 1 and 10. Keratin 1 defects are often associated with PS variants while keratin 10 defects are associated with NPS variants.
Epidermolytic hyperkeratosis Definition
Epidermolytic hyperkeratosis is also called bullous congenital ichthyosiform erythroderma. This condition is a relatively rare autosomal ichthyosis which is dominant. It was first described in 1902 by Brocq as bullous a ichthyotic erythroderma to distinguish it from the congenital ichthyotic erythroderma. The defect which causes the condition is found to be in the genes for keratin 1 and 10.
