The condition of having growths on the skin surface that are wart-like and noncancerous is called seborrheic keratosis. It can also be called barnacles of old age, senile warts, seborrheic verruca, and senile keratosis. This noncancerous growth on the skin starts in the key constituent of the epidermis called keratinocyte. Aging is a factor that can contribute to the appearance of seborrheic keratosis.
The term “seborrheic keratosis” is a combination of the adjective form of the word seborrhea (which refers to the skin disorder that causes flaky, scaly, and itchy, reddish skin and affects the sebum-gland rich areas), and keratinocyte (the part of the epidermis that creates keratin) and the suffix -osis which is used to mean abnormal.
The characteristics of seborhheic keratoses may vary like how it goes with their colors ranging from light tan to black. From a tiny mark to over one inch across, the measurement may vary.
It can appear like a melanoma skin cancer or a wart although it has no viral origins. 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 unknown why there are seborrheic keratoses appearing on some individuals. Nonetheless, ultraviolet rays can be pointed out given the fact the sun-exposed body parts are affected. This areas include arms, neck, face, and back. Also, genetics can also be a factor to be considered on determining the cause of seborrheic keratosis.
The horny pearls and the embedded cysts can be attributed to its upshot on the skin. It is suggested to consult a skin expert if you have doubt. One way to determine this condition is by means of skin biopsy.
Epidermal nevi can be mistaken for seborrheic keratosis because of their semblance It is best to have dermatoscopy given the fact that it may look like warts or condylomas. 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.
Just as long as there is a right diagnosis to the condition, no more treatment is needed. Picking at the lesions brings a small risk on invading the surrounding area of the infection. If there is an intensely sharp itchiness on the growth, cryosurgery is needed.
For those who have small lesions, the best treatment is light electrocautery. There are many ways like cryotherapy, electrodessication and curettage, and shave excision that can be taken by those who have bigger lesions. Correct treatment is necessary so that there would be not much scars visible on the skins of affected individuals save for dark-skinned ones.
