Abstract
The skin is an organ covering the external surface of the body. It functions as a protective barrier against injury, infection, and ultraviolet radiation. It also plays a role in regulating body temperature, vitamin D production, and sensory processing of environmental stimuli. Radiation dermatitis is a skin condition associated with therapeutic ionizing radiation exposure. This may develop during radiation of primary skin cancer or as a sequela of radiation of deeper structures, as the rapidly dividing cells of the skin are prone to radiation injury during treatment. Acute radiation dermatitis generally develops within the first few weeks of treatment as visible erythema and may progress to blistering and desquamation of the skin. Most of the changes are reversible. Chronic radiation dermatitis appears after a latent period of months to years. Poikilodermic changes such as telangiectasia or mottled hyper-/hypopigmentation are characteristic, as well as skin atrophy.
