A 39-year old Malay male presented with a history of photosensitivity following exposure to sunlight. The skin became itchy for about 20 minutes and was followed by blister formation. The affected skin subsequently showed signs of peeling off. He has had similar experience since the age of 12 years and has learned to avoid unnecessary exposure to sunlight since then. Examination showed areas of...

Photosensitivity in childhood is caused by a diverse group of diseases. A specific sensitivity of a child's skin to ultraviolet light is often the first manifestation or a clinical symptom of photodermatosis. It might indicate a serious underlying systemic disease such as lupus erythematosus or dermatomyositis, or a rare group of genetic skin disorders like Xeroderma pigmentosum, Cockayne syndr...

CONTEXT The reason that only some patients with lupus erythematosus (LE) develop autoantibodies to SS-A/Ro and SS-B/La antigens and photosensitivity is unknown. One hypothesis is that both events are related to the level of expression of these antigens in the skin. OBJECTIVE AND DESIGN To test this hypothesis, we measured the expression of the 52-kd SS-A/Ro, 60-kd SS-A/Ro, and 48-kd SS-B/La a...

PURPOSE Photosensitivity, a reaction of the brain to external photic stimulation, can be graded from 1 to 4, and is most frequently seen in the first decades of life. This study investigated photosensitivity in children with epilepsy. METHODS A retrospective study performed in the neuropaediatric department of the largest paediatric hospital in Kiel, treating patients at all medical care leve...

A man whose psoriasis was well controlled on methotrexate treatment developed pellagra-like photosensitive dermatitis when he started taking haloperidol. Reactivation of his dermatitis was observed with methotrexate as a recall photosensitivity phenomenon. This false photosensitivity reaction of methotrexate is an important but rarely encountered adverse effect. A possible interaction between m...

A 32-year-old woman was treated with long-term voriconazole therapy for recurrent aspergillosis associated with chronic granulomatous disease. A short time after commencement of voriconazole therapy, a severe photosensitivity reaction developed. Continued voriconazole exposure led to the development of multifocal facial squamous cell carcinomas. The photosensitivity reaction resolved after the ...

The aim of this study was to assess the prevalence of exposure to topical nonsteroidal anti-inflammatory drugs (NSAIDs), particularly ketoprofen, in a convenience sample of the population, to obtain estimates of the incidence of severe photosensitivity leading to hospitalization, and to assess causative factors in three catchment areas: the Paris metropolitan area, the Lombardy region (Italy) a...
