Seborrheic keratoses are common skin growths that typically appear as waxy, scaly, and slightly raised lesions on the skin.
Key Visual Characteristics of Seborrheic Keratoses
Seborrheic keratoses are distinctive in their appearance, often described by their unique textures and range of colors. They are non-cancerous growths that develop gradually over time.
Color and Pigmentation
The color of seborrheic keratoses can vary significantly, often reflecting different stages or individual skin tones. They are usually found in shades of:
- Brown
- Black
- Light tan
Texture and Elevation
One of the most defining features of seborrheic keratoses is their texture and how they protrude from the skin. These growths commonly appear:
- Waxy: Giving them a somewhat "stuck-on" appearance, as if a piece of wax has been applied to the skin.
- Scaly: Indicating a rough or flaky surface.
- Slightly raised: They are not flat with the skin but have a noticeable elevation.
Common Locations and Development
Seborrheic keratoses tend to appear in specific areas of the body and develop gradually:
- Face: A very common site for these lesions.
- Neck: Often found in areas exposed to the sun or friction.
- Chest: Can appear on the upper torso.
- Back: Frequently seen on the upper and mid-back.
These growths typically emerge gradually, meaning they do not appear suddenly but rather form and grow slowly over time.
