Is Seborrheic Keratosis The Same As Seborrheic Dermatitis?

Seborrheic Keratosis (SK) and Seborrheic Dermatitis (SD) are two skin conditions that are often confused because they can both cause scaly, itchy skin. While they may have similarities, these two conditions are actually quite different. Here’s a closer look at the key differences between SK and SD:

Seborrheic Keratosis

Seborrheic Keratosis is a common, noncancerous skin growth that appears as a scaly, raised lesion. It is most often found on the face, chest, back or shoulders. SK can range in color from white to yellow to black and is usually slightly raised above the surface of the skin. While SK can be itchy, it is not normally painful.

Seborrheic Dermatitis

Seborrheic Dermatitis is a common skin condition that causes scaly, itchy skin. It is most often found on the scalp, face, chest or back. SD can also cause dandruff. The exact cause of SD is unknown, but it is thought to be related to an overgrowth of a yeast that normally lives on the skin. SD is usually treated with medicated shampoo or cream.

Key Differences

• Location: SK usually appears on the face, chest, back or shoulders while SD typically affects the scalp, face, chest or back.
• Color: SK can be various colors including white, yellow or black. SD usually causes red, scaly patches.
• Itching: Both SK and SD can cause itching. However, SK is not normally painful.
• Cause: The exact cause of SD is unknown but it is thought to be related to an overgrowth of a yeast that normally lives on the skin. SK is not caused by an overgrowth of yeast.
• Treatment: SD is usually treated with medicated shampoo or cream. SK does not require treatment but can be removed for cosmetic reasons.

Although SK and SD can both cause scaly, itchy skin, there are some key differences between these two conditions. If you think you may have either SK or SD, it’s important to see a board certified dermatologist for an accurate diagnosis and appropriate treatment.Seborrheic keratosis and seborrheic dermatitis are two common skin conditions that can cause similar symptoms. While they share some common features, they are actually quite different.

Seborrheic keratosis is a non-cancerous growth that can develop on the face, chest, or back. The growths are usually yellow, brown, or black, and they can vary in size. They often have a waxy or scaly texture, and they may be itchy.

Seborrheic dermatitis is a skin inflammation that can cause reddish, scaly patches on the scalp, face, and other areas of the body. The condition is often accompanied by dandruff. Seborrheic dermatitis is thought to be caused by an overgrowth of a yeast that naturally lives on the skin.

While seborrheic keratosis and seborrheic dermatitis can cause similar symptoms, they are different conditions. Seborrheic keratosis is non-cancerous and does not require treatment. Seborrheic dermatitis is a skin inflammation that can be treated with over-the-counter antifungal creams or prescription medications.
