Seborrheic keratosis is a common, harmless, non-cancerous skin condition. It usually appears as red, brown, yellow, gray or very dark brown hair growth on the back, shoulders, chest or face.

Also called basal cell papillomas or seborrheic warts, seborrheic keratoses appear anywhere on the skin except the palms, soles, and mucous membranes. Equivalent

Neck, legs, neck, arms and legs and sometimes on the face. Some appear black but are actually a very dark brown.
Seborrheic keratosis may look like a wart, but it is different from a wart. Warts are caused by viruses such as the human papillomavirus (HPV). According to Dermnet NZ, seborrheic keratosis is unlikely to be caused by HPV or other viruses. They are not contagious.
Seborrheic keratosis appears from middle age. Some have only one, but usually several. Seborrheic keratosis is not contagious.
People in the United States have seborrheic keratosis. It can occur at any age, but is more common after age 50.
What Is Barnacle?
Some lesions may be light and flat, such as solar lentigo, also known as sunspots or “heart” marks.
Seborrheic keratosis lesions are rarely painful, but can be painful depending on their location. Do not pick or pull as this can cause bleeding, swelling and possible infection.
Stucco keratoses are often small, pale papules or bumps with a raised texture, especially around the lower legs and ankles.
Dermatosis papulosa nigra appears as many small, dark-colored papules or bumps. Sores often appear on the face. Equivalent
Preventing And Treating Benign
Seborrheic keratosis and skin cancer lesions can be difficult to differentiate. Therefore, anyone who notices new lesions or skin changes should consult a doctor.
People with many types of seborrheic keratosis may want to make an annual appointment with their dermatologist to check for changes that could be cancerous.
If the dermatologist does a biopsy, they usually remove the seborrheic keratosis at the same time.
The doctor applies liquid nitrogen to the growth with a spray gun or cotton swab. The sores will freeze and disappear in a few days. A blister may form, which eventually dries to the surface.

The doctor cuts the wound with a scalpel without touching the layer below the surface of the skin. The collected cells are then sent to a laboratory for biopsy.
In electrocautery — also called electrosurgery — the surgeon uses electricity to block the growth under local anesthesia. In curettage, the doctor uses a scoop-shaped surgical instrument to remove the inflammatory growth.
Doctors usually use a local anesthetic to numb the area. However, on the face, they will use less current and not reduce the area.
Heats the upper layer of the skin and heats the lower layer to stimulate the growth of new collagen fibers. Non-invasive surgery is less invasive and works by stimulating new collagen growth.

The Food and Drug Administration (FDA) has approved a 40% hydrogen peroxide solution for keratosis, which appears to be safe and effective. Minor adverse effects may include scaling, swelling, and skin discoloration.
Lemon juice or vinegar can irritate the skin and cause sores to dry out and crust over. However, there is no evidence that it is safe or effective.
Some ingredients, such as tea tree oil, can cause allergic contact dermatitis, an immune system reaction that causes itching and swelling around the site.
Anyone concerned about a lesion should see a doctor, who can check that it is not melanoma and prescribe appropriate treatment.
Seborrheic Keratosis: Symptoms, Treatment, And Causes
However, in rare cases, the sudden onset of seborrheic keratosis may be associated with an underlying disorder such as digestive cancer, lymphoma, or leukemia. In this case, it is called the Leser-Treélat sign.
A sudden eruption of multiple seborrheic keratoses can occur during pregnancy, during chemotherapy, and with various inflammatory skin disorders.
However, since it is difficult to differentiate between skin cancer and seborrheic keratosis, it is best to consult a doctor, especially if multiple lesions appear in a short period of time or the lesions change.
If the doctor suspects melanoma or is unsure, he or she may recommend a biopsy for examination under a microscope.

Seborrheic keratosis is rarely cancerous, but it shares genetic characteristics with some types of cancer. Researchers hope that the genetic processes used by lesions can help scientists learn more about certain types of cancer.
In most cases, seborrheic keratosis does not require treatment, but people can remove it if it rubs on clothing or feels uncomfortable. Doctors may remove one when taking a biopsy for skin cancer. Options include minor surgery, laser therapy, and cryotherapy. Your doctor can advise you on the best course of action.
Seborrheic keratosis skin color can be black, tan, brown, yellow, gray or very dark brown. They are waxy or thick like warts. Some feel like they stick to the skin, while others lie flat. They vary in size from the pin point to more than 1 inch (about 2 mm to 3 cm). It usually grows slowly.
But some features can be shared with malignant lesions. Differentiation from skin cancer is difficult, so it is important to see a doctor about new or unknown lesions.

Seborrheic keratosis is a harmless lesion that appears on the skin, especially in older people. It can occur on any part of the body except the soles of the feet and the palms of the hands.
They can be yellow, brown, brown or leathery in color. Some appear black but are actually dark brown in color. Sticking to the skin can raise it, but there are also flat ones.
Seborrheic keratosis and skin cancer can be difficult to differentiate. Therefore, people should consult a doctor if they notice new lesions or if the lesions change.

What Whale Barnacles Know
Gray whales have learned to approach whale-watching boats to avoid being harassed by humans, it has been claimed.
Video footage documenting the behavior in the Ojo de Libre Lagoon off the coast of Baja California, Mexico shows a gray whale with the cetacean’s head removed by the captain of a small boat. “I’ve done the same whale over and over again,” Paco Jimenez Franco told the US news site. “It’s really exciting for me.”
Whale lice or psyamids — yellow, crab-like creatures that crawl on the animals’ heads — are beneficial to whales, feeding on algae on their bodies and feeding on skin and wounds. However, it is also considered disturbing to the animal.
“I think gray whales have a love-hate relationship with whale life,” said Mark Carwardine, a British zoologist with extensive experience in the area. “Their skin is very sensitive, and it must have been terrifying to catch thousands of these tiny creatures or move them with their very sharp claws.”

He added: “It hurts when lice grab your finger – it feels like little claws.”
Franco took the flea off the whale’s head for the first time. “When I cleared the chief, he contacted me again so I could proceed,” he said. According to Franco, the same individual whales have returned time and time again to “progress.”
Like relatively slow-moving large whales, including humpbacks and right whales, gray whales — which can grow up to 15 meters (50 feet) — are particularly vulnerable to parasites. They also have burrows as they feed on underwater amphipods.
In Baja California, gray whales are revered for their strange behavior toward boats, despite being heavily hunted in the 20th century. Because of their ruthlessness in fighting, their tactics include killing the nurse. calves. To make sure the adults get close enough to harpoon. Another predator of whales is the orca.

While he couldn’t confirm that reaching out to humans for help was a new behavior in whales, Carwardine said he hadn’t seen it before. “Even if you have to vote by the hundreds, the Pope certainly doesn’t care when people vote,” he said.
