Seborrheic keratosis is the presence of noncancerous wart-like growths on the skin surface. It is also known as barnacles, senile wart, senile keratosis, and seborrheic verruca. Keratinocyte or an overgrowth of keratin is the beginning part of this benign growth on the surface of the skin. As people age, seborrheic keratosis becomes more apparent just like with liver spots.
The clinical term “seborrheic keratosis” is the combination of word seborrheic (characterized by the skin disorder causing scaly, itchy, and flaky, reddish skin affecting the sebum-gland rich areas), and the producer of keratin known as keratinocyte and the suffix -osis meaning abnormal.
The characteristics of seborhheic keratoses may vary like how it goes with their colors ranging from light tan to black. They have measurements from small ones up to more than one inch across.
It can appear like a melanoma skin cancer or a wart even though it has no viral origins. A seemingly pasted on appearance is the typical description of seborrheic keratosis granted that the only part involved in the top layer of the epidermis.
It is not clear why seborrheic keratosis exists on some individuals. However, the cause can be attributed to ultraviolet rays since it exists on areas of the body that are usually exposed to the sun. 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. When in doubt, it is still the best thing to do to consult a dermatologist. Skin biopsy is one good solution for this.
In appearance, seborrheic keratosis is somehow the same as epidermal nevi. The same way goes with warts and condylomas, so it is really advisable to undergo a dermatoscopy. 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. Small risk of local infection is brought about by picking at the lesions. One good technique is cryosurgery if there is a sharp itchiness brought by the growth.
For those individuals who have tiny lesions, light electrocautery is the best treatment to be undergone. Conversely, bigger lesions necessitates various treatments such as cryotherapy, shave excision, and electrodessication and curettage. Rightful treatment is necessary so that there would be not much scars visible on the skins of affected individuals save for dark-skinned ones.
