Lichen planus is a relatively common disease that affects areas of the skin and frequently (but not always) the inside of the mouth, resulting in distinctive skin or oral lesions. This disease often appears on the wrist, and it can also affect the scalp, genitals, and nails. It’s important to note that lichen planus itself is not an infectious disease, so it cannot be passed from one person to another by any means. It is also not a type of cancer, although the presence of oral lichen planus may increase the risk of developing oral cancer.
