Sunburn is an acute, delayed, and transient inflammatory response of normal skin after exposure to UVR from sunlight or artificial sources. By nature it is a phototoxic reaction. Sunburn is characterized by erythema (Fig. 10-1) and, if severe, by vesicles and bullae, edema, tenderness, and pain. This image shows painful, tender, bright erythema with mild edema of the upper back with sharp demarcation between the sun-exposed and sun-protected white areas. Note large atypical melanocytic nevi. The patient is at risk for developing malignant melanoma.
