But most of the skin lumps we develop will be benign. Here are some of the most common, and how to tell them apart. Moles, or naeviare the most common skin lesions. They can be brown, black, pink, the same colour as the surrounding skin, or even blue if the melanocytes are clustered deep in the dermal inner layer of the skin.
Most moles are flat but they can also be raised. While some people have moles at birth, they usually begin to appear during Skin Still Bleeds - Glenn Fletcher - Out Of It and keep developing through Skin Still Bleeds - Glenn Fletcher - Out Of It your 40s, when they start to slowly disappear again.
The number of moles you have is partly controlled by genetics, but is also influenced by your environment. Lots of sun exposure leads to more moles, and so can using certain medicationssuch as those that suppress your immune system. Many more look like moles in their early stages. If the lesion is asymmetrical, multi-coloured or has other signs of melanoma, the doctor will excise it for further testing.
Having many moles is the strongest predictor of a high melanoma risk, so people with many moles are often advised to have regular skin checks with a dermatologist. For the rest of Sexual Religion - Rod Stewart - Time, self-examinations are recommended. Seborrhoeic keratosessometimes inelegantly called senile warts or barnacles, are another common benign skin lesion. These are considered part of the normal skin ageing process.
These wart-like growths can begin to appear in your 30s and 40s. They can erupt suddenly after a sunburn or a bout of dermatitis, or gradually appear for no discernible reason. If many itchy seborrhoeic keratoses erupt suddenly, it is occasionally a sign of an internal cancer. Very rarely, basal or squamous cell carcinomas arise within a pre-existing seborrhoeic keratosis.
Seborrhoeic keratoses themselves are harmless, but can be prolific — some people have hundreds — and they increase in number as the years go by. Their colour ranges from pale yellow to black. They can be waxy, warty or scaly, and anywhere between 1mm and several centimetres across. Those that are dark and large can look alarming, but when seen under a dermoscope they usually have a characteristic brain-like or banksia-like appearance and are easily distinguished from skin cancers.
If in doubt, your doctor will take a biopsy to investigate further, since a melanoma can occasionally simulate a seborrhoeic keratosis. Seborrhoeic keratoses can be annoying if they snag on clothes or get in the way of your razor, and some people find them unsightly. In these cases they can be removed by freezingcutting them offburning, laser surgery, chemical peels or excision with scalpel or scissors.
A cyst is a round lesion made of a capsule filled with keratin the structural material that makes up the outer layer of our skinsebum the oil from our skinfluid or pus-like material. Firm or squishy to the touch, they are totally benign. Sometimes cysts form when injured skin gets tucked in to form a pocket and the maturing and dying skin cells build up inside it. Other cysts are formed when epidermal cellsnormally found on the surface of the skin, proliferate in the deeper dermis and fill up in a similar way.
Some cysts form when a hair follicle, sweat duct or mucous gland becomes blocked and fluid builds up behind the blockage. Ganglion cysts form when fluid from nearby joints leaks into a capsule under the skin. Several genes can make you more susceptible to forming cysts of various sorts. The material inside a cyst can range from watery to soft-cheese-like, and can be odourless or smelly. Usually the only way to get rid of a cyst permanently is to surgically remove its encapsulating wall.
If it is only drained of fluid, it will just fill up again. Fortunately, a dermatologist can usually remove a cyst in a short procedure with a little local anaesthetic.
This is demonstrated in the weirdly popular videos of Dr Pimple Popper which, by the way, you might not want to watch at lunch. Haemangiomas are another benign, usually painless skin lesion, formed from an excessive growth of blood vessels in the skin. They are usually firm lumps and can present as cherry angiomas, venous lakes or spider angiomas. Depending on how deep in the skin they are, they can be red, purple or even deep blue. Cherry angiomas Skin Still Bleeds - Glenn Fletcher - Out Of It round or oval, sharply defined, bright red bumps, usually less than half a centimetre wide.
If found on the lip, they are called venous lakes. Spider angiomas also have a tiny central red lump, but with red lines capillaries wriggling outwards like the legs of a spider. They usually appear on the face and upper body. If many spider angiomas suddenly appear, it can be a sign of high oestrogen or poor liver function, but, as a rule, isolated spider angiomas are not a cause for worry.
Rarely, angiomas mimic amelanotic non-pigmented nodular Retalation - Kéta* - Metz Pour Le Temps Futur - Éclectisme Électronique Mixé Par Kéta. These need to be excised for further testing.
In that case, the angioma can be frozen with liquid nitrogen, burnt off with electrosurgeryor treated with lasers. Dermatofibromas are firm small nodules, which are sometimes itchy and might be mistaken for an insect bite. In fact, most probably they also evolve from some types of insect bites.
They are usually 1cm across or smaller, seem to be in the surface layer of the skin and, if you pinch one, a dimple will Ill Always Be In Love With You - Titus Turner - Sound Off in it.
On pale skin, they range from pink to light Jenny Jenny - Jerry Lee Lewis - The Killer 1963-1968, and on darker skin from dark brown to black, and can Őrülj +! - Mex - Őrülj+ paler in the middle. Like seborrhoeic keratoses, dermatofibromas are harmless but can be annoying.
In this case, they are removed by simple surgical excision. Lipomas are not, strictly speaking, a skin lesion at all. Often appearing similar to cysts, lipomas are actually slow-growing tumours of fat cells surrounded by a fibrous capsule. Like cysts, they are very common and not malignant. Some lipomas might arise after a blunt injury to the site, but the mechanism causing that is not well understood.
The egg or dome-shaped lipoma usually feels rubbery and moves around easily under the skin. This makes them easy to diagnose clinically, though doctors sometimes use a deep skin biopsy to be sure. Most lipomas are not painful to touch, but they can grow as big as 10cm across and restrict movement of nearby muscles or joints. A newly appeared mole or an existing mole that starts growing or changing colour should be checked.
If the lesion bleeds very easily — at a touch — get it looked at as soon as possible. Painful lumps are another sign all is not right. YorkTalks — York, York. Lest we forget? Born to rewild!
