How do common skin lesions look? (with pictures)

The majority of skin lesions are benign, but when a new lesion or mark appears on our skin, it can be difficult to tell whether it is dangerous. If you have any suspicions about a mark, mole or lesion, you should ask your doctor to check it. Nevertheless, it is useful to know how the common skin lesions look like to be able to recognise them.
In this post, we explain all about the most common skin lesions (with photos) and their main characteristics.

Seborrheic Keratosis

Seborrheic Keratosis, sometimes called senile wart, is a non-cancerous condition that occurs as a light brown, black or tan growth on the surface of the skin. These are usually harmless but may sometimes get irritated or be aesthetically unappealing. They can be removed, if necessary.

Dermatofibroma is a benign skin tumor that appears as a firm, round, brownish to red-purple growth usually found on the legs.

Epidermal inclusion cyst (EIC)

An epidermal inclusion cyst is a common skin cyst, sometimes called sebaceous cyst, even though it arises from hair follicles, not oil glands. The cyst contains a foul-smelling, cheese-like substance formed from degenerating keratinocytes. They can become red and aggravated if the substance enters the dermis, an occurrence which is often mistaken for an infection. Asymptomatic cysts don’t require treatment. Excision can be used to remove a cyst if desired.
