Understanding Skin Lesions: Types, Causes, and Treatments

Overview of Skin Lesions

Skin lesions are minor bumps or growths on the skin that are usually harmless. They can appear as red or skin-colored patches, varying in size and texture. These bumps might be itchy, dry, or filled with pus, resulting from allergies, infections, skin conditions, or even skin cancer. In most cases, they resolve naturally, but consulting a healthcare professional is advisable if they persist or cause discomfort. Common causes include eczema, psoriasis, insect bites, or other skin disorders.

Common Types of Skin Lesions

Several skin bumps, such as acne, are widespread and can range from small to large, often painful, according to the American Academy of Dermatology.

Boils are infections of hair follicles that usually drain and heal on their own.

Corns and calluses develop as thickened skin, frequently found on hands and feet.

Serious Conditions That Need Medical Attention

Persistent or unusual bumps caused by bacterial infections or other illnesses require prompt evaluation. Notable examples include:

Chickenpox, common in children, presents as fiery red spots across the body and needs urgent care.

Impetigo, characterized by crusted blisters, is highly contagious among children.

MRSA infections can cause swollen bumps with white centers due to resistant bacteria.

Skin Lesions Linked to Cancer

Actinic keratosis features dry, crusty patches on sun-exposed skin, often scaly and itchy, with colors ranging from gray to brown.

Basal cell carcinoma appears as shiny, reddish bumps that may bleed and are often painful.

Squamous cell carcinoma manifests as sores or red patches in sun-exposed areas, originating from upper skin layers.

Melanomas are irregular, multicolored moles requiring medical evaluation.

When to Seek Medical Help and Treatment Options

While most skin bumps are benign, seek medical advice if they cause pain, change in appearance, or worsen over time.

Doctors will examine, review your medical history, and may perform a biopsy if necessary.

Removal techniques include freezing, surgical excision, or medications, especially for cosmetic concerns or infected lesions.

Contagious conditions like chickenpox or MRSA may require specified medications or home remedies under medical guidance.

Follow-up visits are essential to monitor treatment progress and adjust as needed.
