Skin Mole Types

The word mole is often used to describe any kind of irregularity or abnormality in the skin. In fact it covers a large range of different skin abnormalities and each one needs to be treated and addressed in a different way.

Out of all skin mole types you will be more familiar with the benign congenital variety also known as nevi. These are caused by pigmented skin cells grouping together in one area of the skin. There are usually harmless and are mostly present from birth although they can appear later on as well during the first 20 years.

Skin Mole Types – Common

Nevi – Usually benign pigmented skin in small circular spots around the body.
Freckles – Darkened flat spots that usually darken after sun exposure and are common with fair or red haired individuals.
Dysplastic Nevi – Also known as atypical moles these are moles that are irregular in shape, size and texture. These moles are more sensitive to sunlight exposure and may develop into skin cancer if over exposed.
Skin Tags – Soft small flaps of skin usually found on the neck, in the armpits or on the groin.
Seborrheic Keratoses – Wart like fleshy, brown or black spots more common in the older generation. They are usually round or oval in shape and look “stuck” on to the skin.

All of the above mole types are benign and have no medical reason for removal. They are found naturally and commonly on most people and do not pose any kind of threat as they are. Some may be emotionally distressing and some may be irritated by shaving or rubbing and these are usually removed because of this.

Skin Mole Types – Uncommon

Pyogenic Granulomas – raised bluish black or red raised marks caused by growth of the capillaries and swelling. This type of mole usually only occurs after an injury. These usually disappear over time but you can have surgery to remove them.
Keratoacanthomas – Round flesh colored growths with a depressed centre which contain a paste like substance. They can also disappear over time and will often leave scarring. You will need to get these checked out by your doctor to check for melanoma.
Keloids – Smooth and firm large growths that form after an injury where the wound was. Certain people will be more likely to develop Keloids than others who may never develop them. It is unusual for a Keloid to develop and most treatments are ineffective. You can get corticosteroid injections to flatten them or you may wish to undergo surgery.
Dermoid cyst – A benign tumor that can include fragments of bone and cartilage. They usually contain hair, sweat glands and sebaceous glands and may be removed surgically.

All of the above examples of the different skin mole types are examples of benign moles. These are not cancerous moles by nature. However, if you notice one develop changes or if you develop an uncommon mole you should visit your doctor as soon as possible to have your mole tested for cancerous cells.
