Types of Skin Lesions and Its Causes and Treatments

Types of Skin Lesions and Its Causes and Treatments

A skin lesion is the part of the skin that has an abnormal growth and has a different look from its surrounding area. They are often the bumps, patches, ulcers, and sore or colored areas of the skin. Although most skin lesions are harmless, some can be signs and warnings of skin cancer.

If you notice changes in the appearance of your skin, you can consult the best dermatologist in East New York. Please contact Doral Health and Wellness Dermatology Center.

There are two categories of skin lesions, which are primary and secondary. The primary skin lesions are abnormal skin conditions that are already present at birth. Such as freckles and moles. While secondary skin lesions are the result of manipulated or irritated primary skin lesions. For example, a mole is scratched until it bleeds, the resulting lesion is now a secondary skin lesion. Examples of secondary skin lesions include crusts, ulcers, sores, and scars.


This is a chronic skin condition, but symptoms can be managed. Eczema is very common and itchy, red patches can appear on your skin. They can also form and grow on any part of your body.


Acne appears as whiteheads, blackheads, or pimples, although it could sometimes be harmless, it can also be bothersome when it leads to scarring. Acne develops when your pores are clogged with dirt, dead skin cells, and your skin’s natural oil.


When your skin gets injured, a watery liquid called serum leaks from your damaged skin. This forms a bubble called blisters. Do not try to pop or burst your blister because it can get infected.


Impetigo is a highly contagious skin infection caused by a bacterium. The bacteria infect the outer layers of your skin called the epidermis. This condition often affects your face, arms, and legs. The infection can begin as minor cuts, insect bites, or as a rash.


If you have allergic reactions, it can cause hives. Hives usually look like a red, bumpy, and itchy rash. But it usually goes away on its own.


These are circular or oblong patches that are darker than the skin surrounding it. Make sure that you have your moles checked from time to time to rule out skin cancer. Check for differences in your moles and talk to your doctor when you notice any changes.


Psoriasis is a chronic autoimmune condition that affects your skin cells. The buildup of these cells causes scaling on your skin’s surface, with bumpy red patches. They can grow on any part of your body, but they usually appear on your scalp, elbows, knees, and lower back.

Actinic keratosis

These are the dry scaly patches on your skin that are damaged due to years of exposure to the sun, but these patches are usually not a serious condition. These are often found on the face, lips, ears, scalp, neck, or the back of your hands.


Ringworm is a common skin infection that is caused by a fungus. This skin infection is called ringworm because of its appearance which is shaped like a ring.  The fungi that cause this infection can live on your skin and on household items such as clothing, bedding, and towels.


The most common causes of skin lesions may be as follows:

  • Virus – like herpes simplex, human immunodeficiency virus, human papillomavirus
  • Bacteria – like staphylococcus, streptococcus
  • Fungi – like candida albicans
  • Allergic reaction – side effects of certain medications such as corticosteroids or chemotherapy
  • Contact with irritant substances
  • Unprotected sun exposure
  • Severe burns
  • Insect bites
  • Vitamin deficiencies
  • Systemic diseases
  • Infectious diseases
  • Liver and kidney disease


Diagnosis begins with a physical examination and medical history. Your medical provider will assess the color, size, shape, depth, and location. Dermoscopy can also be performed to examine skin lesions. And sometimes further tests might be needed to perform, especially if malignancy is suspected.


Treatment for skin lesions varies depending on the type of skin lesions, and if malignancy is present. Some benign lesions may not need to be treated and can be managed through regular checkups. If malignant, surgery can be performed to remove the lesion.

The most common treatments for skin lesions may include:

  • Medication
  • Surgery
  • Home care/remedies

Some skin lesions are usually not a source of worry. But if you notice skin lesions that are suspicious, immediately book an appointment with your dermatologist to diagnose your condition.
