Rough, thick epidermis with exaggerated skin lines. This is often a characteristic of scratch dermatitis and atopic dermatitis.
A hollow, crusted area caused by scratching or picking at a primary lesion.
An erosion is a secondary skin lesion where the epidermis is lost, leaving a moist, shallow depression in the skin. It results from damage to the skin surface, such as scratching or picking at a primary lesion like a blister or ulcer. Erosions typically appear red and are prone to infection.
A primary lesion occurs as a result of a spontaneous manifestation of a pathological process - includes macules, papules, nodules, tumours, plaque, vesicles, bullae, pustules, wheals, burrows and telangiectasiaA secondary lesion occurs as a result of the evolution of a disease, or from external trauma - they may evolve from primary lesions - includes scales, crust, atrophy, lichenification, erosion, excoriation, fissure, ulceration, scars, eschars, keloidsIf it is hard to distinguish just think that if you don't look after a disease, or skin condition correctly then secondary skin problems can occur - just like how if you don't apply moisture to sunburn it can blister and peel
primary lesion is a macule, papule, pustlie, vesicle secondary lesion is a ulcer, crust, scar, skin atrophy, excoriation
eczema
An area of skin that has become very thin and wrinkled. Normally seen in older individuals and people who are using very strong topical corticosteroid medication.
Vascular proliferation in the context of lichenized skin likely refers to an increased blood vessel formation within the skin affected by lichenification. Lichenification is a skin condition characterized by thickening of the skin and accentuated skin markings due to chronic rubbing or scratching, often seen in conditions like eczema or dermatitis. The combination of vascular proliferation and lichenification may suggest a chronic inflammatory process affecting the skin.
A dried collection of blood, serum, or pus. Also called a scab, a crust is often part of the normal healing process of many infectious lesions.
A raised lesion filled with pus. A pustule is usually the result of an infection, such as acne, imptigeo, or boils.
hyperleratotic skin lesion
Sometimes the purpose of skin lesion removal is to excise an unsightly mole or other cosmetically unattractive skin growth.
