Definition
The blisters are vesicles with a diameter greater than 10 mm, detected on the skin level and characterized by the collection of clear liquid (serous or serum-ematic). These skin lesions arise below the outer layer of the epidermis.
Blisters can be caused by severe burns, burns, radiation, exposure to extreme cold (eg tissue damage sustained by freezing), intense friction or rubbing of a particularly sensitive and exposed portion of skin.
The skin can react with the formation of bullous lesions even after contact with irritants or natural stinging agents (allergic or irritative contact dermatitis).
Bubbles can develop as a reaction to some drugs, to an insect bite or to contact with different allergens. The appearance of blisters can also occur in patients suffering from autoimmune diseases (such as pemphigus vulgaris), viral infections (such as chickenpox, cold sores, herpes zoster and impetigo) and acne.
Depending on the cause that causes the onset of the blister, this can be accompanied by pain, redness or itching.
