Keratosis
Specialty	Dermatology, medical genetics

Keratosis (from kerat- + -osis)^[1] is a growth of keratin on the skin or on mucous membranes stemming from keratinocytes, the prominent cell type in the epidermis. More specifically, it can refer to:

actinic keratosis (also known as solar keratosis)
chronic scar keratosis
hydrocarbon keratosis
keratosis pilaris (KP, also known as follicular keratosis)
seborrheic keratosis

Actinic keratoses are pre-malignant growths. Seborrheic keratoses are not pre-malignant.
