Excerpt

Seborrheic keratosis is a prevalent benign skin condition made up of immature epidermal keratinocytes. The condition manifests in different forms, ranging from a faintly colored, superficial patch to a brown to black, scaly papule or plaque with a distinctive "stuck-on" appearance. Seborrheic keratoses are primarily seen in adults and older individuals. Most patients typically observe their initial seborrheic keratosis during their middle adult years. They exhibit gradual growth in both size and quantity over several years. This condition becomes more common as individuals age, and it affects almost all adults who are 60 years of age or older.
