Seborrheic keratosis is the presence of noncancerous wart-like growths on the skin surface. It can also be named as barnacles of old age, senile warts, seborrheic verruca, and senile keratosis. Keratinocyte is the beginning part of this benign growth on the surface of the skin. Seborrheic keratosis becomes more evident as people grows old just like with age spots.
The medical term “seborrheic keratosis” is a combination of the adjective seborrheic (referring to the condition that affects the sebum-gland rich areas and brings itchy, flaky, reddish and scaly sensation), and keratinocyte (which produces keratin on the skin) and the suffix -osis which means abnormal.
Seborrheic keratoses may have varying characteristic just like with their colors from brown to black. They measure from very tiny to over an inch across and round or oval in shape, and flat or elevated.
Even though it has no viral origins, it can look like a wart and even melanoma skin cancer. A seemingly pasted on appearance is the ordinary description of seborrheic keratosis granted that the only part involved in the top layer of the epidermis.
It is still unclear why there are seborrheic keratoses appearing on some individuals. However, the harmful rays coming from the sun can be pointed at because involved are the parts of the body that are exposed to the sun in most cases. This areas include arms, neck, face, and back. One more contributor to its occurrence is genetics.
This can be easily recognized through its appearance that resembles embedded cysts or horny pearls. When in doubt, it is still the best thing to do to consult a dermatologist. Skin biopsy is one good solution to this.
Seborrheic keratosis looks greatly like epidermal nevi. It is compulsary for you to have dermatoscopy since it also resembles condylomas and warts. When the growths appear on the penis or on the genital skin, it is best to go for a skin biopsy to distinguish it from condylomas.
