Abstract
Keratosis (from "keratinocyte", the prominent cell type in the epidermis, and , abnormal) is a growth of keratin on the skin or on mucous membranes. More specifically, it can refer to:
- actinic keratosis (also known as solar 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.
