Keratosis seborrheica, also known as seborrheic keratosis, is a common benign skin condition that primarily affects older individuals. It is characterized by the development of noncancerous growths on the skin, typically appearing as brown, black, or tan patches or bumps. These growths can vary in size, shape, and texture, and often have a waxy or scaly appearance.
The prevalence of keratosis seborrheica increases with age, with studies suggesting that it affects up to 83% of individuals aged 60 and above. However, it can also occur in younger individuals, albeit less frequently. The exact cause of this condition is not fully understood, but factors such as genetics, sun exposure, and hormonal changes may contribute to its development.
Keratosis seborrheica is generally harmless and does not require treatment unless it causes discomfort or affects one's appearance. While it may resemble other skin conditions or even skin cancer, it is important to consult a dermatologist for proper diagnosis and to rule out any underlying health concerns.
