Phototoxic dermatitis is caused by contact or ingestion of some photosensitizing substance. Phytophotodermatitis affects anyone, who gets in contact with some plants containing furocoumarins and later gets exposed to sunlight (dermatitis striata praetensis of Hebra).

Photoallergic dermatitis appears after exposure to some photosensitizing agent (usually drugs) applied on the skin and following exposure to sunlight. The reaction develops in senzitized persons by delayed hypersensibility reaction.

Acute solar dermatitis is caused by severe UV irradiation of a sensitive skin. In phototoxic and protoallergic reactions some photosensibilizing agens is effective as well (some drugs, desinfecting agents, various plants etc.)

Polymorphous solar eruption affects insolation areas, more often women; prutitus, papules, vesicles.
