Dermatological lesions refer to abnormal changes or abnormalities that occur on the skin. These lesions can manifest in various forms, sizes, colors, and textures and may be indicative of various skin conditions or diseases. This article aims to provide an overview of dermatological lesions, including the types of lesions and some common examples seen in dermatology.

There are three main types of dermatological lesions:

Primary Lesions: These are initial or fundamental lesions that develop on previously unaffected skin. Examples include macules, papules, nodules, plaques, vesicles, bullae, pustules, and wheals.

Secondary Lesions: Secondary lesions result from changes that occur to primary lesions or due to external factors such as scratching or infection. Examples include erosions, ulcers, scales, crusts, scars, and excoriations.

Tertiary Lesions: Tertiary lesions are rare and typically occur in specific conditions or diseases. Examples include keloids, skin tumors, and certain types of chronic ulcers.

Several common skin lesions are frequently encountered in dermatology, including:

Macules: Flat, discolored spots on the skin, such as freckles or age spots.

Papules: Small, raised bumps on the skin, such as acne lesions.

Plaques: Raised, flat patches of skin that are often associated with conditions like psoriasis.

Vesicles: Small, fluid-filled blisters, such as those seen in herpes or chickenpox.

Pustules: Pus-filled lesions, typically seen in bacterial infections like impetigo or acne.

While several lesions are commonly observed in dermatology, one of the most prevalent is the macule. Macules are small, flat discolorations on the skin that can vary in color, including red, brown, or black. They are often associated with conditions like freckles, sunspots, or melasma. Macules can be a result of hyperpigmentation, vascular abnormalities, or skin trauma.

Dermatological lesions encompass a wide range of abnormalities and changes that occur on the skin. Understanding the different types of lesions and recognizing common examples is crucial for dermatologists and healthcare professionals in diagnosing and managing various skin conditions. If you notice any unusual or persistent skin lesions, it is recommended to seek medical attention for proper evaluation and appropriate treatment.
