[Study of action spectrum of papulovesicular light eruption (PVLE)].
Eight patients suffering from papulovesicular light eruption (PVLE) were phototested for reproduction of skin lesions with FL20SE and FL20BLB. Of the 8 patients, 50.0% developed typical lesions of PVLE at the test site by provocative phototesting with FL20SE (3 daily exposure of 2MED). In these patients, similar lesions were induced by the provocative test with FL20BLB for 2 consecutive days without filter, but no eruptions were induced when a sharp cut filter UV-35 was used. In conclusion, it is important to consider not only UVB but also the border spectrum between UVB and UVA (320-340 nm) as the action spectrum of PVLE.
