Keratosis is a general term used to describe a variety of skin conditions characterized by the buildup of keratin, a protein that makes up skin, hair, and nails. This buildup can cause rough, scaly patches, bumps, or other skin changes. Keratosis can be harmless or a sign of a precancerous condition, depending on the specific type.
Here are some common types of keratosis:
- Actinic keratosis: Also known as solar keratosis, this condition is a precancerous growth caused by excessive sun exposure. It appears as a rough, scaly patch or bump on the skin.
- Seborrheic keratosis: This is a common, noncancerous skin growth that appears as a raised, oval or round spot on the skin. They are often brown or black and can be itchy or bleed.
- Keratosis pilaris: This is a harmless skin condition that causes small, rough bumps, often on the arms, legs, and buttocks. It's caused by a buildup of keratin in the hair follicles.
It's important to note that keratosis can have different causes and symptoms. Therefore, it's always best to consult a dermatologist for diagnosis and treatment recommendations.
