GUIDOLIN, Fernanda et al. Prevalence of cutaneous findings in systemic sclerosis patients: experience of a teaching hospital. An. Bras. Dermatol. [online]. 2005, vol.80, n.5, pp. 481-486. ISSN 1806-4841. http://dx.doi.org/10.1590/S0365-05962005000600005.
BACKGROUND: Systemic sclerosis or scleroderma is a rare collagen disease presenting several cutaneous manifestations. OBJECTIVE: To study the prevalence of cutaneous manifestations in systemic sclerosis and its subtypes (limited form, diffuse form and overlap syndrome). METHODS: We studied 32 patients with scleroderma (20 with the limited form; 8 with the diffuse form and 4 with overlap syndrome) considering skin sclerosis, Raynaud's phenomenon, digital scars, telangiectasia, leucomelanoderma (pigmentary changes), microstomy, calcinosis and pruritus. RESULTS: We found skin sclerosis and Raynaud's phenomenon in 100% of patients, digital scars in 65.6%, telangiectasia in 43.7%, pigmentary changes in 43.7%, microstomy in 31.25%, pruritus in 28.1% and calcinosis in 12.5%. No statistically significant differences were observed in the limited and diffuse forms of scleroderma (p = 1.0 for digital scars; p = 0.69 for teleangiectasis; p = 0.22 for microstomy; p = 1.0 for calcinosis and pruritus). The overlap syndrome was not different from the isolated forms (limited and diffuse) of systemic sclerosis. CONCLUSION: The most common skin manifestations in scleroderma are skin sclerosis and Raynaud's phenomenon and calcinosis is the rarest. The other cutaneous manifestations presented similar frequency in all subtypes of scleroderma.
