Causes of solar exudative erythema multiforme.
Symptoms of solar exudative erythema multiforme.
The disease mainly occurs in spring and summer. In most cases, hyperemic edematous spots or nodules appear on exposed areas (face, neck, outer sides of arms and legs). Elements (mainly plaques) 0.5-1.5 cm in size tend to grow peripherally, rise slightly above the skin, and have a round or oval shape. The center of the elements is bluish-pink, and the circumference is pink-red. If vesicular elements appear, they contain serous and sometimes hemorrhagic fluid. The vesicle cover quickly bursts, erosions form, their surface is covered with a hemorrhagic and yellowish-gray crust. Itching and burning are felt in the lesions.
Solar erythema multiforme exudative erythema is often combined with polymorphic photodermatosis, solar erythema and other photodermatoses.
