Polymorphous Light Dermatosis: Symptoms, Complaints, Signs

The following symptoms and complaints may indicate polymorphous light dermatosis:

Initially, itching occurs, followed by patchy redness of the skin. Thereafter, the following efflorescences (skin changes; skin bloom) may occur:

  • Bullae (blisters)
  • Papules (vesicles)
  • Papulo-vesicle – a mixture of papule and vesicle (vesicle) represents.
  • Plaques (areal or plate-like substance proliferation of the skin).

Predilection sites (body regions where the disease occurs preferentially) after intense sun exposure are:

  • Décolleté
  • Arms, stretch side
  • Back of the hand
  • Legs
  • Torso
  • Face
  • Very rarely scatter reactions occur

Symptoms occur delayed after hours to days, so not directly at exposure. If sun exposure is avoided, the efflorescences disappear within a few days without consequences.

The same skin lesions always persist in an affected person.

After repeated exposure to light (summer), the skin becomes accustomed to the radiation doses.
