dyskeratosis

 [dis″ker-ah-to´sis]
abnormal, premature, or imperfect development of the keratinocytes. adj., adj dyskeratot´ic.

dys·ker·a·to·sis

(dis'ker-ă-tō'sis),
1. Premature keratinization in individual epithelial cells that have not reached the keratinizing surface layer; dyskeratotic cells generally become rounded and they may break away from adjacent cells and fall off.
2. Epidermalization of the conjunctival and corneal epithelium.
3. A disorder of keratinization.
[dys- + G. keras, horn, + -osis, condition]

dyskeratosis

Abnormal, excessive or imperfect KERATINIZATION of cells of the EPIDERMIS. DYSPLASIA of a squamous epithelium.

dyskeratosis

abnormal keratinization characterized by incomplete conversion of skin cells to keratin, usually characterized by scaling and parakeratosis

dyskeratosis

Abnormal process which, in the eye, results in hornification of the epithelial layer of the conjunctiva or cornea. It may be hereditary or due to irritation (e.g. radiation) or to prolonged drug administration in the eye. It appears as a dry white plaque (called leucoplakia or leucokeratosis). It may be benign or malignant, in which case it must be surgically excised. See pterygium.

dys·ker·a·to·sis

(dis-ker'ă-tō'sis)
Premature keratinization in individual epithelial cells that have not reached the keratinizing surface layer.
[dys- + G. keras, horn, + -osis, condition]

dyskeratosis (dis´kerətō´sis),

n an irreversible alteration in the maturation of stratified squamous epithelium. Refers to an increase of abnormal mitosis, individual cell keratinization, epithelial pearls within the spinous layer, loss of polarity of the cells, hyperchromatism, nuclear atypia, and basilar hyperplasia.
