Figure 1 Approach to a newly diagnosed patient with cutaneous lupus. The evaluation of a patient with cutaneous lupus begins with assessment of ongoing or prior extracutaneous manifestations. Laboratory investigation and referrals to other specialists (e.g., rheumatology or nephrology) are guided by the history, physical examination, and clinical test results. ANA, anti-nuclear antibody; CBC, complete blood count; CLE, cutaneous lupus erythematosus; CRP, C-reactive protein; ENA, extractable nuclear antigen; dsDNA, double-stranded DNA; ESR, erythrocyte sedimentation rate; SLE, systemic lupus erythematosus.

Figure 2 Approach to a follow-up patient with cutaneous lupus. The follow-up evaluation centers on determining if the patient’s disease is stable or has progressed. Laboratory investigation should be focused on prior laboratory test result abnormalities and screening for occult systemic involvement. ANA, anti-nuclear antibody; CBC, complete blood count; CLE, cutaneous lupus erythematosus; CRP, C-reactive protein; dsDNA, double-stranded DNA; ESR, erythrocyte sedimentation rate; SLE, systemic lupus erythematosus.
