Department of Dermatology, University of Regensberg, Germany.

A 71-year-old woman had noticed the development of blisters on her forehead 4 months before she was referred to our department. Treatment with oral corticosteroids resulted in complete healing, but new blisters subsequently developed on the face, neck and backs of the hands. After the possibility of phototoxic and photoallergic reactions, as well as an abnormal porphyrin profile, had been excluded, the diagnosis of bullous pemphigoid was made by histological and direct immunofluorescent examination. UV-A provocation on the upper arm produced lesions histologically and immunohistochemically typical of bullous pemphigoid. Of particular importance was the fact that the blisters were limited strictly to light-exposed skin areas.

UI	MeSH Term	Description	Entries
D010391	Pemphigoid, Bullous	A chronic and relatively benign subepidermal blistering disease usually of the elderly and without histopathologic acantholysis.	Pemphigoid,Bullous Pemphigoid,Pemphigoids
D010787	Photosensitivity Disorders	Abnormal responses to sunlight or artificial light due to extreme reactivity of light-absorbing molecules in tissues. It refers almost exclusively to skin photosensitivity, including sunburn, reactions due to repeated prolonged exposure in the absence of photosensitizing factors, and reactions requiring photosensitizing factors such as photosensitizing agents and certain diseases. With restricted reference to skin tissue, it does not include photosensitivity of the eye to light, as in photophobia or photosensitive epilepsy.

D014466	Ultraviolet Rays	That portion of the electromagnetic spectrum immediately below the visible range and extending into the x-ray frequencies. The longer wavelengths (near-UV or biotic or vital rays) are necessary for the endogenous synthesis of vitamin D and are also called antirachitic rays; the shorter, ionizing wavelengths (far-UV or abiotic or extravital rays) are viricidal, bactericidal, mutagenic, and carcinogenic and are used as disinfectants.
