Crusts

Crusts are a type of lesion or wound that develops when a layer of skin becomes dry, thickened and cracked. They are often yellowish-brown in color, and can be itchy or painful. They can develop from a variety of causes, such as eczema, psoriasis, fungal infections, or contact dermatitis. They can manifest as scaly, thick patches, or as small, raised bumps. Treatment for crusts depends on the underlying cause, and may include topical creams, oral medications, or light therapy.
