What Are Skin Lesions? Causes And Types Of Skin Lesions

A lesion is an abnormal growth compared to the surrounding skin (1). Lesions may look like bumps, lumps, or patches. A variety of factors can cause them. There are two types of skin lesions (2):

  • Primary Skin Lesions: The abnormal skin growth that is present at birth or develops over time is called primary skin lesion. Moles and blisters are two examples of this type of lesion.
  • Secondary Skin Lesions: These lesions form when a primary skin lesion has been aggravated or manipulated. Scars and crusts are two examples.

A variety of conditions can cause skin lesions. Here are some examples of potential causes and types:

1. Acne

Acne develops when oil and dead skin cells block your pores (3). It results in red, white, or black bumps. Teenagers and young adults are prone to this condition. Hormones, family history, and certain medications may contribute to it. In addition, pricking acne, eating specific foods, stress, and environmental conditions can aggravate the condition (4). Treatments consist of medications and laser therapy.

2. Eczema

Eczema is a skin condition that causes dry, scaly, or irritated skin. Hereditary and environmental factors may cause this chronic condition (5). Eczema can improve or deteriorate over time. Treatment can help manage symptoms, but there is no cure. Consult a doctor if you are having discomfort and pain due to eczema.

3. Blisters

The tiny pockets of fluid that form when the upper layers of the skin are injured are called blisters. They can appear on hands and feet or anywhere on the body. They heal on their own in a few days (6). They don’t require medical attention unless they are severe, caused by burns, or have become infected.

4. Rash

A rash is a group of small or large skin lesions that cover a region of the skin. It can occur for various reasons. Reaction to skin care products is the most common cause (7). The ingredients in these products can irritate the skin. Rashes are harmless and may go away on their own. Some may be persistent due to underlying causes or illnesses. If you experience any symptoms, consult a dermatologist.

5. Cold Sores

Cold sores are fluid-filled blisters that appear on and around your lips (8). Exposure to the scorching sun, chilly wind, or cold can cause them. Other issues like a compromised immune system, fluctuating hormone levels, or stress can also lead to cold sores. These blisters are found in patches. A scab forms when the blisters split, which may last many days. Cold sores normally heal without leaving a scar in two to three weeks. If your symptoms are severe, consult a doctor right away.

6. Hives

Moles form when skin cells grow in clusters instead of spreading evenly throughout the skin. These cells (melanocytes) produce the pigment that gives skin its natural color (10). Moles may turn dark due to sun exposure, during adolescence, and during pregnancy. If the color or appearance of a mole changes, you should see a dermatologist. If your moles bleed, ooze, seem scaly, or become irritating, you should get them checked.

8. Shingles

Shingles cause rashes or blisters on the skin. It is caused by herpes zoster virus, which belongs in the same family of viruses that cause chicken pox (11). It looks like a ring of rashes or blisters in one area of the body and can be painful. Consult a doctor if you suspect a shingles infection. Antiviral drugs must be started to alleviate discomfort and shorten the length of your symptoms.

10. Psoriasis

Psoriasis is a skin disorder that causes red, dry, crusty skin patches coated with silvery scales. These patches are mostly found on the elbows, knees, scalp, and lower back (13). The severity of psoriasis varies widely. It may be a little irritating for some, but it can severely impact the quality of life for others.

You can use oatmeal to relieve irritation or swelling caused by certain skin lesions (15).
