SAURIT, V. et al. Manifestaciones mucocutaneas en pacientes con lupus eritematoso sistemico. Medicina (B. Aires) [online]. 2003, vol.63, n.4, pp.283-287. ISSN 0025-7680.

The objective was to analyze the prevalence of mucocutaneous lesions in patients with systemic lupus erythematosus (SLE). During a 3-year period, we analyzed 77 patients with a diagnosis of SLE. The mucocutaneous lesions were classified into specific and non-specific. We defined skin type, sunlight exposure and photoprotection and correlated these lesions with serology and disease activity. Acute specific lesions were found in 67.5% of the patients, subacute lupus in 6.5% and chronic lesions in 26.0%. The most prevalent non-specific lesions were alopecia (59.7%), photosensitivity (57.1%), Raynaud's syndrome (46.7%), oral ulcerations (15.6%) and livedo reticularis (11.7%). Skin type 3 (35%) and exposure to mild ultraviolet radiation (74%) were seen in the majority of the patients. Appropriate sunlight protection was only used by 47% of the patients. When dermatological lesions and serology were compared, we found a significant association between malar rash, photosensitivity, livedo reticularis and alopecia with the presence of anti-Ro and Raynaud's phenomenon in patients with positive anti-Sm. The presence of malar rash, photosensitivity, Raynaud's phenomenon, diffuse alopecia and livedo reticularis was more frequent among patients with active disease. The prevalence of mucocutaneous manifestations in our population was slightly higher than data reported in other series. The presence of malar rash, diffuse alopecia, photosensitivity and livedo reticularis significantly related with the presence of anti-Ro and Raynaud's phenomenon with anti-Sm. All these lesions were more frequently seen in patients with active disease.
