XII: Diseases of the skin and subcutaneous tissue
The group "Diseases of the Skin and Subcutaneous Tissue" refers to a range of conditions that affect the body's largest organ—your skin—and the layer of fat and connective tissue just beneath it. These conditions can be either congenital or acquired, meaning they can be present from birth, or develop over time due to different factors such as infections, allergies, sun exposure, or underlying diseases. Common symptoms often include rashes, sores, discolouration, tumours, dryness or itchiness. These can occur anywhere on the body and may be accompanied by discomfort or pain. The progression of these diseases varies, but often involves changes to the skin's appearance, texture, and sensitivity. This group of conditions impacts not only the skin and subcutaneous tissue, but can also affect a person's overall wellbeing, including their mental health due to changes in physical appearance or chronic discomfort.
