Background: The frequency of photodermatoses in African Americans has not been well characterized.
Objective: To evaluate the frequency of photodermatoses in African Americans in an academic medical center during a 7-year period. This was compared with that observed in Caucasians seen during the same period. Read More

Background: The idiopathic photodermatoses have been reported to be rarer in tropical Singapore than in countries of higher latitude, with photoaggravated dermatoses and systemic phototoxicity making up most of the photodermatoses seen here. This study aims to reassess the spectrum of photodermatoses seen at the National Skin Centre, Singapore, compared with almost a decade ago, and analyse the clinical and photobiological characteristics, as compared with other countries.
Materials And Methods: We reviewed the clinical data of 141 patients phototested from January 2000 to December 2001, and analysed the epidemiological, clinical and photobiological features. Read More

Photodermatoses are a group of skin diseases primarily caused by, or exacerbated by exposure to ultraviolet and or visible radiation. The effect of sunlight on skin depends on a number of factors including skin colour, skin phototype and the content and type of melanin in the skin. There are only a few studies describing photodermatoses in populations with dark skin. Read More

Photodermatoses can be classified into five general categories: 1) idiopathic photodermatoses, including polymorphic light eruption (PMLE), actinic prurigo, hyroa vacciniforme, chronic actinic dermatitis, and solar urticaria; 2) photodermatoses which are secondary to exogenous agents, including phototoxic and photoallergic reactions; 3) photodermatoses secondary to endogenous agents, mainly the porphyrias; 4) photoexacerbated dermatoses, including autoimmune disease, infectious conditions, and nutritional deficiencies; and 5) genodermatoses. The initial step in evaluating a photosensitive patient is based on a directed personal and family history. The morphology of the eruption, phototests, and in some patients, photopatch tests are essential in focusing the diagnosis. Read More
