A thickening of the cornified cell layer.
Abnormal overgrowth of the horny layer of the epidermis.
Thickening of the outer layer of skin. It may occur as an inherited disorder, affecting the soles of the feet.
Hypertrophy of the horny layer of the epidermis.
This is defined as increased thickness of stratum corneum, either by normal or abnormal keratinocytes. Eg. Lichen Planus
Excessively thickened layer of the stratum corneum composed of orthokeratin (hyperorthokeratosis) or parakeratin (hyperparakeratosis).
a disease resulting in the abnormal growth of the corneous layer of the skin
Increased differentiation of epidermal cells into keratinocytes. This could occur if a part of the skin is rubbed for a long period of time. The resulting callus is caused by a rapid increase in the production of keratinocytes. Hyperkeratosis can also result from disease states such as in psoriasis.
A condition marked by thickening of the outer layer of the skin, which is made of keratin (a tough, protective protein). It can result from normal use (corns, calluses), chronic inflammation (eczema), or genetic disorders (X-linked ichthyosis, ichthyosis vulgaris).
hypertrophy of the cornea or the horny layer of the skin. Also called hyperkeratinization.
