Erythrokeratodermia variabilis (also known as "Erythrokeratodermia figurata variabilis," "Keratosis extremitatum progrediens," "Keratosis palmoplantaris transgrediens et progrediens,"[1]:509 "Mendes da Costa syndrome,"[2] "Mendes da Costa type erythrokeratodermia," and "Progressive symmetric erythrokeratoderma") is a rare autosomal dominant disorder that usually presents at birth or during the first year of life.[1] To date, it is thought to be caused by mutations in genes encoding for connexin channels proteins in the epidermis, leading to the misregulation of homeostasis in keratinocytes. [3]
One type is characterized by generalized, persistent, brown hyperkeratosis with accentuated skin markings, while a second type is localized, with involvement that is limited in extent and characterized by sharply demarcated, hyperkeratotic plaques.[1][4]:565
It can be associated with GJB3[5] and GJB4.[6]
It was characterized in 1925.[7]
