Diffuse non epidermolyti palmoplantar keratoderma (also known as “Tylosis”) is inherited as an autosomal dominant condition and is present from infancy, characterized by a well-demarcated, symmetric, often “waxy” keratoderma involving the whole of the palms and soles.
Black hairy tongue or hyperkeratosis linguae is an alternate term for Leukoplakia.
Ichthyosis is a family of genetic skin disorders characterized by dry, thickened, scaly skin.
