Ichthyosis en confetti, also known as ichthyosis with confetti. congenital reticular ichthyosiform erythroderma (CRIE) and ichthyosis variegata^[1], is a very rare form of congenital ichthyosis in which healthy patches of normal skin co-exist within the abnormal skin areas.^[2] It has been hypothesized that this is the result of a combination of mitotic recombination and natural selection within the skin.^[3] Choate et. al. have shown that mutations in a gene called keratin-10 cause this disorder. They show that mutant keratin 10 accumulates in the nucleolus, a sub-nuclear structure, rather than within cellular intermedite filaments like the wild-type protein. It has been speculated that the presence of mutantkeratin 10 results in increased rates of mitotic recombination, thus in effect leading the disease to effect its own partial "cure".^[2]
