The highest incidence rate was seen in the 45\u201365 year age group. Primary lesion ulceration was seen in 60.2% of patients. The 1-year, 3-year and 5-year survival rates were 85.7%, 34.7% and 13.3%, respectively. In univariate analyses, the 5-year survival rate in patients was significantly associated with ulceration (P\u2009&lt;\u20090.01), clinical stage (P\u2009&lt;\u20090.01) and surgical excision of the tumor (P\u2009&lt;\u20090.01). Cox multivariate regression analysis confirmed that ulceration and clinical stage were independent prognostic factors.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Some clinical characteristics of MM patients in China are significantly different from those of patients in Western countries.
