Seborrheic Keratosis is also called senile wart and is a type of skin growth that starts its working from keratinocytes. This skin growth is non-cancerous and looks same like liver spots that growth on human skin. These spots grow on the skins of people whose range increases and these spots are sometimes called barnacles of people of old age.
The colors of these spots vary from light pink to black color. Their shape is oval or slightly elevated and size is more than 2.5 cm. They look similar to warts, but they are not warts and are not originated from viral origins. They also look similar to melanoma skin cancer, but are much different non-cancerous spots. The top layers of skin are involved in their growth and are described as pasted on appearance on skin.
There are many different classes of Seborrheic keratosis. These classes are common Seborrheic keratosis also called as solid Seborrheic keratosis, reticulated Seborrheic keratosis also known as Adenoid Seborrheic keratosis, Stucco keratosis also known as Digitate Seborrheic keratoses, Clonal Seborrheic keratoses, irritated Seborrheic keratoses and some other classes.
Visual diagnosis method is used to diagnose these spots. This method is used because these darks spots are heard to visualized and differentiate from nodular melanomas. If doctor is not sure about these spots, he should performed skin biopsy. These spots are very difficult to differentiate from lentigo maligna even if dermatoscopy is performed. The spots that look similar to Seborrheic keratoses are epidermal nevi. Actually epidermal nevi are the spots that appear on the skin at the time of birth or near birth. There are some other spots that are also similar to Seborrheic keratoses, these spots include warts and condylomas, but they are different from these spots and skin biopsy is required to differentiate between these spots.
The treatment of these spots is not necessary if they are properly diagnosed. These spots only cause infection on the skin. Usually the main cause of the production of these spots is clothing or jewelry, but they can easily remove from the skin using cryosurgery. There are some lesions that are small in size and can be treated using light electrocautery. But for the larger lesions, the methods of treatment include shave excision or cryotherapy. When these spots are removed from the skin, sometimes darks color skin appears instead of them, but proper method of treatment may remove that skin color from the skin too.
