keratosis palmaris et plantaris

keratosis

[ker″ah-to´sis] any horny growth, such as a wart or callosity.actinic keratosis a sharply outlined wartlike or keratotic growth, which may develop into a cutaneous horn, and may become malignant; it usually occurs in the middle aged or elderly and is due to excessive exposure to the sun. Called also senile or solar keratosis. (See Atlas 3, Part F).keratosis follicula´ris a slowly progressive autosomal dominant disorder of keratinization characterized by pinkish to tan or skin-colored papules on the seborrheic areas of the body that coalesce to form plaques, which may become crusted and secondarily infected; over time, the lesions may become darker and may fuse to form papillomatous and warty malodorous growths. Called also Darier's disease and Darier-White disease.keratosis palma´ris et planta´ris palmoplantar keratoderma.keratosis pharyn´gea horny projections from the tonsils and pharyngeal walls. Called also pharyngokeratosis.keratosis pila´ris hyperkeratosis limited to the hair follicles.keratosis puncta´ta a hereditary hyperkeratosis in which the lesions are localized in multiple points on the palms and soles.seborrheic keratosis (keratosis seborrhe´ica) a benign, noninvasive tumor of epidermal origin, marked by numerous yellow or brown, sharply marginated, oval, raised lesions.senile keratosis (solar keratosis) actinic keratosis.

pal·mo·plan·tar ker·a·to·der·ma

[MIM*148600 & MIM*244850] the occurrence of symmetric diffuse or patchy areas of hypertrophy of the horny layer of the epidermis on the palms and soles; a group of ectodermal dysplasias of considerable variety, and either autosomal dominant or recessive inheritance. Synonym(s): ichthyosis palmaris et plantaris, keratoderma palmare et plantare, keratoderma symmetrica, keratoma plantare sulcatum, keratosis palmaris et plantaris, tylosis palmaris et plantaris

KRT10

A gene on chromosome 17q21 that encodes a type-I (acidic) member of the cytokeratin family, which belongs to the superfamily of intermediate filaments, that with actin microfilaments and microtubules forms the epithelial cell cytoskeleton.
Molecular pathology
KRT10 mutations cause epidermolytic hyperkeratosis.

keratosis palmaris et plantaris

A congenital abnormality of the palms and soles, characterized by a dense thickening of the keratin layer in these regions.See also: keratosis
