Background: Classification of lupus erythematosus (LE) is conflicting as it is carried out from different starting points. Whereas dermatological classifications categorize LE morphologically based on specific cutaneous lesions, rheumatologic classifications are based on symptomatic aspects. Indeed, LE is a systemic autoimmune disease with variable acuity and organ involvement. All cutaneous disease patterns may occur in both limited-cutaneous and systemic LE.Patients and Methods: 76 LE-patients with complete clinical data, clinical photographs and biopsy of cutaneous manifestations as well as paraclinical findings were retrospectively analyzed. Based on a published two-dimensional classification system that considers disease-specific skin manifestations and final disease diagnosis separately, patients' diagnoses were revised and compared with those in medical records. In addition, the extent to which patients could be clustered by diagnosis based on their LE-specific skin manifestations, corresponding histopathological changes, and paraclinical data was investigated.Results: After re-evaluation, the proportion of patients with limited-cutaneous LE decreased from 82% previously to 24%. More than two-thirds of patients indeed showed intermediate or systemic LE. Disease-specific skin manifestations, histologic characteristics and paraclinical data did not cluster with final diagnoses.Conclusions: First, the work underlines the systemic character of the disease. Second, a two-dimensional approach can help overcome classification difficulties in LE, as skin-morphologic and symptomatic aspects can be considered separately.

Dowling–Degos disease (DDD) is a rare autosomal‐dominant genodermatosis with limited treatment possibilities. Although the efficacy of ablative laser therapy has been reported, we sought to examine the efficacy of fractional versus full ablative laser therapy in a female patient with DDD in a split‐side report. We treated the lesions on the right side of the patient's upper abdomen with an ablative fractional CO2 laser and the lesions on the left side of the upper abdomen with a full ablative Er:YAG laser (erbium‐doped yttrium aluminium garnet laser) three times at monthly intervals. After three laser sessions, the lesions treated with the Er:YAG laser showed a complete response, whereas the fractional CO2 laser treatment was less effective. After the three treatments were performed, the right side of the patient's upper abdomen and portions of her lower abdomen and chest were also treated with the Er:YAG laser in full ablation mode with the same settings. After 1 year of follow up, there was no recurrence observed. Lasers Surg. Med. © 2018 Wiley Periodicals, Inc.
