What is Progressive symmetric erythrokeratodermia?

Progressive symmetric erythrokeratodermia is a rare, autosomal dominant skin condition that manifests soon after birth with erythematous, hyperkeratotic plaques that are symmetrically distributed on the extremities, buttocks, and face, but sparing the trunk. No other clinical symptoms nor mental or physical signs are usually associated with the condition.

This condition is also known as Darier-Gottron syndrome, progressive symmetric erythrokeratoderma, progressive symmetric erythrokeratodermia of Gottron and erythrokeratodermia variabilis et progressiva.

Less than one hundred cases have been reported to date.
