Epidermodysplasia verruciformis

Epidermodysplasia verruciformis (also called Lewandowsky-Lutz dysplasia), colloquially known as tree man illness is an extremely rare autosomal recessive genetic hereditary skin disorder associated with a high risk of carcinoma of the skin. It is characterized by abnormal susceptibility to human papillomaviruses (HPVs) of the skin. The resulting uncontrolled HPV infections result in the growth of scaly macules and papules, particularly on the hands and feet. It is typically associated with HPV types 5 and 8, which are found in about 80 percent of the normal population as asymptomatic infections, although other types may also contribute.
