Epidermolytic ichthyosis (EI) specifically refers to a hereditary skin disorder that is characterized by varying degrees of blistering and subsequent reactive scaling of the skin. The underlying histopathology shows mid-epidermal splitting and hyperkeratosis, together referred to as epidermolytic hyperkeratosis (EHK). Depending on the nature of the causative mutation, the symptoms may vary from mild blistering upon friction to severe erosions or widespread warty scaling ("porcupine man"). A palmoplantar keratoderma (excessive callus formation on palms and soles) and/or hair abnormalities may be present in some forms of the disorder.
The term epidermolytic ichthyosis was agreed upon by the International Ichthyosis Consensus Group in 2009 and replaces the older, confusing labels of bullous congenital ichthyosiform erythroderma (Brocq) and epidermolytic hyperkeratosis.
A number of disorders show epidermolytic hyperkeratosis, including EI, superficial epidermolytic ichthyosis bullosa and desmosomal disorders such as McGrath ectodermal dysplasia-skin fragility syndrome. Much confusion has resulted from use of the term EHK to refer to the disorder now known as epidermolytic ichthyosis.
