Seborrheic keratosis is a rather common benign skin growth seen in older individuals. Seborrheic keratosis can be rather unsightly and nasty, but the growths are not cancerous. On the other hand, occasionally, seborrheic keratosis can be difficult to diagnose and differentiate from melanoma, a very serious type of skin malignancy.
If your skin changes all of a sudden, or you see the appearance of growth, you must always have it examined by a health care provider / dermatologist. The condition is usually painless and needs no treatment. Nonetheless, you may opt to have the growths removed if they get inflamed by clothing or for cosmetic purpose.

Treatment Options For Seborrheic Keratosis
- A dermatologist will diagnose seborrheic keratosis by examining the lesion. In case of any doubt, your doctor will excise a small portion of the growth and send it for biopsy. The biopsy will be examined under a microscope. This helps identify the growth as either seborrheic keratosis or malignant melanoma.
- By and large, seborrheic keratosis does not require any treatment. Nevertheless, your dermatologist may make a decision to get rid of any growths which have a doubtful appearance or are causing you physical or emotional discomfort.
- There are three commonly used methods of removal for Seborrheic Keratosis – cryo-surgery, electro-surgery, and curettage.
- When your doctor employs cryo-surgery, the growth is frozen off using liquid nitrogen.
- Electro-surgery makes use of an electrical current to get rid of the lesion. The area is numbed before the procedure.
- Curettage is a scoop-like surgical gadget which scrapes the growth. Curettage is occasionally used with electro-surgery.
