“…In recent years, our group has demonstrated that pathologic skin reactions can be induced in 54% of patients with various subtypes of LE, when applying standardized protocols of provocative phototesting (12). Interestingly, as confirmed by other investigators (13)(14)(15), the development of UV light-induced skin lesions is considerably slower and the persistence is longer than in other photodermatoses, such as polymorphous light eruption (PLE).…”

“…21,22,25 In contrast to previous observations, most of the patients with LET reacted to UV-A and UV-B irradiation, as found for other forms of cutaneous LE. 19,23,25,26 A few days after UV exposure, erythema and itching developed, followed by characteristic morphologic skin lesions of LET with histological changes similar to those in primary lesions ( Figure 5). Patients with LET had been found to be even more photosensitive than patients with SCLE 19 and, in our study, experimental phototesting revealed characteristic skin lesions in 28 (70%) of the patients; 10 (56%) of the 18 tested patients reacted to UV-A and UV-B irradiation, 16 (40%) of the 40 patients to UV-A only, and 15 (38%) of the 40 patients to UV-B only.…”

“…O uso de bloqueadores solares de amplo espectro pode trazer benefício adicional pela capacidade de proteção contra UV-A, em algumas lesões cutâneas como as lesões subagudas 15 (D), bem como no melhor prognóstico relacionado às lesões renal e trombocitopênica …”
