What is Seborrheic Keratosis?
Seborrheic keratosis, also known as seborrheic verruca or basal cell papilloma, is a common noncancerous skin growth. It usually appears as a waxy, brown, black, or tan growth on the face, chest, shoulders, or back. Seborrheic keratoses are typically painless and do not require treatment unless they become bothersome or for cosmetic reasons.
Here are some key points about seborrheic keratosis:
Causes:
The exact cause of seborrheic keratosis is unknown. However, genetic factors, sun exposure, and aging are believed to play a role in its development.
Symptoms:
Seborrheic keratoses are usually painless and don’t cause any symptoms unless they are irritated or rubbed. They appear as raised, rough or warty growths with a stuck-on appearance. The color can vary, ranging from tan to black.
Diagnosis:
A dermatologist can usually diagnose seborrheic keratosis by examining the growth. In some cases, a skin biopsy may be performed to rule out other skin conditions or to confirm the diagnosis.
Treatment:
Most seborrheic keratoses do not require treatment. However, if the growths are causing discomfort or if there are concerns about their appearance, treatment options include:
- Cryosurgery: Freezing the growth with liquid nitrogen to remove it.
- Curettage: Scraping off the growth with a specialized instrument.
- Electrosurgery: Using an electric current to burn off the growth.
- Laser therapy: Using laser light to destroy the growth.
- Topical treatments: Prescription creams or lotions may be used to reduce the appearance of seborrheic keratoses.
