<unk>  (also called Lewandowsky-Lulz dysplasia or  Lulz-Lewandowsky<unk>  is an extremely rare skin disease characterized by the growth of scaly macules and papules, particularly on the hands. Named after doctors Felix Lewandowsky and Wilhelm Lulz, the condition usually begins in childhood and has no known cure.
It is believed to be caused by the human papillomavirus and is most strongly associated with strains 5 and 8, although others may also contribute. Genetic predisposition is also thought to partly explain why the disease is so rare, as<unk>  papillomaviruses are often found (15-20%) in normal skin with no increased incidence of cancer.
