Psoriasis is a chronic inflammatory skin disease that can occur anywhere on the body, and the cause may be related to genetic sensitivity. Psoriasis occurring on the face is called facial psoriasis, which may appear as corn to green bean sized dotted red spots in the early stage and gradually expand to form patches and plaques with silvery white scales. When the scales are scraped away, a translucent light red film can be seen, called the film phenomenon, and continued scraping away the film can be seen dotted bleeding. Acute psoriasis on the face often appears as drop-shaped or nail-cap-sized infiltrative erythema or papule, often due to daily facial cleansing, so the scales are relatively few or even no scales, and the clinical characteristics are similar to seborrheic dermatitis or lupus erythematosus.
