“…Both disorders are characterized by the delayed appearance and long (up to 48 h) duration of wheals [7,12,13,14,15,16]. However, in fixed solar urticaria lesions develop (and can be reproduced by phototesting) only on fixed areas of the skin [12,13,14,15], whereas in persistent solar urticaria they appear on any irradiated skin site [7,16].…”

“…However, in fixed solar urticaria lesions develop (and can be reproduced by phototesting) only on fixed areas of the skin [12,13,14,15], whereas in persistent solar urticaria they appear on any irradiated skin site [7,16]. Just as with solar angioedema, a nonhistaminergic pathogenic mechanism was hypothesized as the cause of both disorders that were poorly responsive to oral antihistamines.…”

Angioedema is a hereditary or acquired disease characterized by localized non-pitting swelling of the subcutaneous tissue which can affect either skin or mucous membranes. Acquired angioedema can often be related to a heterogeneous group of etiological factors including physical stimuli, although up to 38% of cases remain idiopathic. We describe 5 patients who developed an angioedema following sun exposures. All patients reported an intensely stinging angioedema strictly limited to face and extremities, when exposed to solar light. Urticarial wheals were never observed or reported by patients, and oral antihistamines proved to be of no help in preventing or improving the condition of lesions. Laboratory and phototesting data allowed ruling out all other acquired or inherited diseases characterized by photosensitivity. We propose that solar angioedema should be considered a novel clinical entity.

“…B. beim Schlafen in der Sonne, können auch die Lippen und die Zunge anschwellen [27].Die Quaddeln bilden sich spontan im Allgemeinen innerhalb von wenigen Stunden zurück [25]. In seltenen Fällen wurde eine Latenzzeit von mehreren Stunden zwischen dem Ende der Bestrahlung und dem Auftreten der Quaddeln und eine Persistenz der Quaddeln von mehr als 1 Tag beobachtet [1,2,37].…”

“…Das histopathologische Bild der Lichturtikaria entspricht weitgehend dem anderer Urtikariavarianten.Gelegentlich wird das Auftreten einer leukozytoklastischen Vaskulitis im Rahmen der Lichturtikaria beschrieben [2]. Bei wenigen Patienten konnte dies durch immunelektronenoptische Untersuchungen dargestellt werden [43].…”

Solar urticaria serves as a model to illustrate the photodiagnostic approach in rare photodermatoses and to demonstrate how patients can be effectively helped by prophylactic and therapeutic intervention. To accomplish these tasks, advanced knowledge and experience in photodermatology is required, along with equipment which is often available in specialized centers only. A list is attached listing the dermatology departments with photodiagnostic units in Germany, Austria, and Switzerland.
