Photodermatitis, sometimes referred to as sun poisoning or photoallergy, is a form of allergic contact dermatitis in which the allergen must be activated by light to sensitize the allergic response, and to cause a rash or other systemic effects on subsequent exposure. It is distinct from sunburn.
光過敏症には、日光への曝露によって引き起こされる、または悪化するさまざまな症状、疾患、状態（光皮膚症）が含まれます。これらは5つのカテゴリに分けられます：primary photodermatosis、exogenous photodermatosis、photo‑exacerbated dermatoses、metabolic photodermatosis、genetic photodermatosis。 Photosensitivity refers to various symptoms, diseases, and conditions (photodermatoses) caused or exacerbated by exposure to sunlight. It is classified into five categories: primary photodermatosis, exogenous photodermatosis, photo-exacerbated dermatoses, metabolic photodermatosis, and genetic photodermatosis.
