Additionally, photosensitivity and cutaneous manifestations characteristic of SLE have been observed to be more prevalent in patients with SLE-psoriasis overlap compared to those with SLE alone [8]. The presence of anti-Ro antibodies has been strongly associated with photosensitivity in SLE, and a small study involving four patients with SLE-psoriasis overlap reported a higher prevalence of anti-Ro antibodies in these individuals compared to SLE patients without psoriasis [19]. This evidence concerns the gene CALR and systemic lupus erythematosus.
