Prurigo is a generic term for skin reactions responsible for itching. Prurigo is characterized by the presence of small crusty bumps on the skin, called "papules", or small raised bumps on the skin appearing to contain the liquid, called "vesicles." These lesions are often accompanied by scratching. This term does not characterize a disease itself. There are several types of prurigo, some of which resemble pathologies of lichen origin.


Prurigo occurs as follows:
  • very severe itching;
  • the presence of papules;
  • damage due to scratching. These lesions turn brown because of irritation.


To define the origin of prurigo, the patient should undergo a thorough physical examination, which also concerns the mucous membranes. An examination will also be conducted to determine the context in which the patient was contaminated.


Treatment depends on the cause of prurigo. Sometimes local treatment is used containing corticosteroids, or drugs of the class of antihistamines to decrease the sensation of scratching. Usually scratching tends to maintain or worsen the disorder, hence the need to act on it.
