Abstract
A 69-year-old woman developed pruritic erythema on her face, ears and dorsal side of the hands 2 weeks after starting prochlorperazine. She showed positive photo tests to 2.5J/cm2, 5J/cm2 and 10J/cm2 UVA but not to UVB up to 120mJ/cm2. Photo patch tests revealed positive responses for 0.1% and 1% prochlorperazine with 2J/cm2 UVA irradiation and 1% prochlorperazine with 80mJ/cm2 UVB irradiation. No erythematous response was observed by patch tests with 0.01%, 0.1% and 1% prochlorperazine. She was diagnosed with photosensitivity due to prochlorperazine. The present case is the second case of photosensitivity due to prochlorperazine in Japan as far as we could tell from the literature.Skin Research, 12: 199-202, 2013
