Seborrheic Keratosis


Benign Skin Tumors

Seborrheic keratoses are the most common of benign skin tumors in older individuals. They usually begin as sharply defined, flat, light brown lesions and, as they grow, will develop an uneven, warty surface with multiple plugged follicles.

Typically having the appearance of being stuck on the skin, seborrheic keratoses can vary in color from pale brown with pink tones to dark brown or black. They can itch, grow and bleed, and can become inflamed when caught on clothing.

Seborrheic keratoses are benign; however, secondary tumors such as squamous cell carcinoma or malignant melanoma may develop within the lesion. They originate in keratinocytes, the predominant cells in the epidermis, and occur more frequently in sunlight-exposed areas of the body.
