Ichthyosis Bullosa of Siemens (IBS) is an autosomal dominant disorder characterized by mild hyperkeratosis and blister formation. The blistering is superficial, and areas of peeling of the skin are known as the 'Mauserung phenomenon'. IBS shows similar features to those in epidermolytic hyperkeratosis, but can be distinguished by the absence of erythema.
