ABSTRACT
The aim of this retrospective study was to investigate the epidemiology, yield of investigations and proportion of patients who develop systemic lupus erythematosus (SLE) among the subsets of cutaneous lupus erythematosus (LE) in the Singapore Asian population. One hundred and twenty-five patients were diagnosed with cutaneous LE on clinico-pathological correlation, of which 73 had discoid lupus erythematosus (DLE), eight had subacute cutaneous LE (SCLE), 22 had acute LE lesions and the remainder had other less common forms of cutaneous LE. Histology was consistent with LE in 94.4% and suggestive in 4.8%. Direct immunofluorescence was positive in 61% of DLE, 86% of SCLE and 80% of acute LE cases. Antinuclear antibody (ANA) was present in the majority of acute LE (85%) and SCLE (88%) but only in 25% of DLE. Eight patients (11%) presenting with DLE had definite SLE at first presentation and two (2.7%) subsequently several months later. Of these patients, six had only mucocutaneous and serological criteria but two had major organ involvement. Five SCLE patients (63%) fulfilled the criteria for SLE, including two with major organ involvement.
