Seborrheic keratosis is a common, non-cancerous skin growth that often appears as a raised, waxy, and slightly raised spot. These growths are benign and don’t pose a health risk, but they can sometimes be cosmetically bothersome.
Appearance and Characteristics:
Appearance:
Seborrheic keratoses typically appear as brown, tan, or black spots that look stuck on the skin, often described as having a waxy or pasted-on appearance.
Size and Shape:
They can vary in size, from a few millimeters to a few centimeters across, and can be round, oval, or elongated.
Texture:
The surface can be smooth, slightly raised, or have a scaly, waxy texture.
Location:
They commonly appear on the trunk, face, and back, and can also be found on other areas of the body.
Non-cancerous:
It’s important to note that seborrheic keratoses are not related to skin cancer and don’t pose a risk to health.
Causes and Risk Factors:
Age: Seborrheic keratoses become more common with age.
Genetics: A family history of these growths can increase the likelihood of developing them.
Sun Exposure: Prolonged sun exposure may play a role in their development.
Friction: Areas prone to friction or rubbing, like clothing folds, may have more seborrheic keratoses.
Symptoms:
Painless: Generally, seborrheic keratoses are painless.
Irritation and Itching: They can sometimes become irritated or itchy, especially if they are rubbed by clothing or other factors.
Bleeding: In some cases, they can bleed, particularly if they are irritated or scratched.
