Bullous congenital ichthyosiform erythroderma, also known as epidermolytic ichthyosis and bullous ichthyosiform erythroderma (and formerly known as epidermolytic hyperkeratosis), is a rare congenital disorder of keratinocytes presenting with blistering at birth and then with hyperkeratosis later in life.
Is erythroderma genetic?
This condition is inherited in an autosomal recessive pattern , which means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition.
Why is it called Harlequin syndrome?
When the nerve bundles are injured, they are not able to communicate with half of the face and body properly. Therefore, that half of the body is not able to respond to stimuli such as exercise by flushing and producing sweat. This causes the Harlequin sign that is associated with this syndrome.

If the collodion is good, the film is semi-transparent, of a bluish opal-like appearance. Many of the unpleasant markings in collodion pictures may have their origin in the gutta percha.
