XII: Diseases of the skin and subcutaneous tissue
L10-L14: Bullous disorders
Bullous disorders are a group of skin conditions that are characterized by the formation of blisters or bullae, which are fluid-filled sacs on the skin. These disorders can be caused by various factors, including genetic mutations, autoimmune reactions, or infections. Bullous disorders can be contagious in certain circumstances, such as when caused by bacterial or viral infections that can be transmitted through direct skin-to-skin contact. Symptoms commonly include the appearance of blisters, which can vary in size, and can occur anywhere on the body. Some people may also experience itchiness or pain around the blistered areas. Bullous disorders are chronic and tend to progress over time, often with periods of worsening and improving symptoms. Although these conditions primarily affect the skin, they can sometimes impact other heath systems, particularly if blisters rupture and become infected.
