In 1968, Waisman1 described patients in Florida who experienced intense pruritus of the lateral aspects of the elbows after exposure to sunlight in the summer. Solar pruritus, also known as brachioradial pruritus, has been seen primarily in the tropical climates in patients with outdoor occupations or avocations.2 We describe a patient with widespread solar pruritus with an action spectrum in the visible light range whose symptoms resolved with the use of oral antihistamines.
