New Subtype of Solar Urticaria?

Abstract

A patient is presented with solar urticaria (SU) with an action spectrum of 285–550 nm. The patient showed a positive passive transfer test and a negative reverse passive transfer test. Since such a type of SU is not described in Harber’s classification, we suggest that this patient shows a new subtype of SU. A combination of UVA/UVB phototherapy proved successful.

“… 50 Therefore, many patients do not fit into such classifications. 51 It should also be noted that there is no pathogenic difference between the different types reported.…”
