Hypertrichosis lanuginosa congenita
Type of disease: Rare conditions
Hypertrichosis lanuginosa congenita is a congenital (present from birth) skin disease characterized by excessive lanugo (very fine, soft, unpigmented) hair covering the entire body, with the exception of the palms, soles, and mucous membranes. The hair can grow to be 3 to 5 cm in length. This condition appears to follow an autosomal dominant pattern of inheritance.
