Acute or chronic skin damage caused by short wavelength electromagnetic radiation (x-rays or gamma rays).
1.3.5 Radiation Dermatitis
Grading & Level of Importance: B
Aetiology & Pathogenesis
DNA damage from high energy radiation.
Signs & Symptoms
Varies with acuity:
- Acute radiation dermatitis: erythema 10 days after exposure.
- Chronic radiation dermatitis: poikiloderma (hypo- and hyperpigmentation, atrophy and telangiectasia occurring more than 2 years after exposure.
Acute and chronic radiation dermatitis.
Most acute radiation dermatitis heals completely; chronic radiation dermatitis leads to scarring and thus permanent changes.
In chronic radiation dermatitis, there is a risk of developing radiation ulcers and radiation keratosis and rarely, squamous cell carcinomas or other radiation-induced tumours.
History, clinical features.
Prevention & Therapy
Acute radiation dermatitis: topical corticosteroids, sometimes systemic corticosteroids for their anti-inflammatory action.
Chronic radiation dermatitis: light protection, sometimes excision of specific lesions.
