Definition
The vesicles are small lesions, circumscribed and detected with respect to the skin plane. They arise below the outermost layer of the epidermis; in particular, they almost always originate in the intraepidermal area (in the thickness of the epidermis) or between the epidermis and the dermis.
The vesicles have a diameter less than 10 mm; otherwise, the skin lesion is called a bubble.
The vesicles are light in color and contain a clear serous or serum-ematic liquid (note: if they contained pus, then a turbid liquid, they would be pustules).
The vesicles are characteristic of skin diseases (eg pemphigus, impetigo, etc.), herpetic infections and irritative or allergic contact dermatitis.
Blisters can also appear in the case of insect bites or drug intolerance.
