Follicular Follicular<unk> , also known as keratosis pilaris (KP), is a skin condition characterized by excessive development of keratin in hair follicles, resulting in rough, cone-shaped, elevated papules. The openings are often closed with a white plug of encrusted sebum. When called phrynoderma the condition is associated with nutritional deficiency or malnourishment. This condition has been shown in several small-scale studies to respond well to supplementation with vitamins and fats rich in essential fatty acids. Deficiencies of vitamin E, vitamin A, and B-complex vitamins have been implicated in causing the condition. By other specific site *Plantar<unk>  is<unk>  of the sole of the foot.

Hereditary *Epidermolytic<unk>  (also known as "Bullous congenital ichthyosiform erythroderma," "Bullous ichthyosiform erythroderma," or "bullous congenital ichthyosiform erythroderma of Brocq") is a rare skin disease in the ichthyosis family affecting around 1 in 250,000 people. It involves the clumping of keratin filaments. *Multiple minute digitate<unk> , a rare cutaneous condition, with about half of cases being familial *Focal acral<unk>  (also known as "Acrokeratoelastoidosis lichenoides,") is a late-onset keratoderma, inherited as an autosomal dominant condition, characterized by oval or polygonal crateriform papules developing along the border of the hands, feet, and wrists. *Keratosis pilaris appears similar to gooseflesh, is usually asymptomatic and may be treated by moisturizing the skin. Other<unk>  lenticularis perstans (also known as "Flegel's disease") is a cutaneous condition characterized by rough, yellow-brown keratotic, flat-topped papules.
