We compared genetic landscape including tumor mutational burden between the two forms of indolent and agressive KS.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Aggressive KS tumours had a significantly higher TMB and a larger cumulative number of deleterious mutations than indolent KS tumours. In addition, all aggressive tumours had at least three deleterious mutations, whereas most indolent tumours harboured only one or no predicted deleterious mutations. Deleterious mutations listed in the Cancer Gene Census were detected exclusively in patients with aggressive disease. An analysis of somatic copy\u2010number alterations (SCNA) revealed a tendency towards higher number of alterations in aggressive KS.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>These data suggest that SCNA alterations and an increase in mutational burden promote aggressive KS and that it might be more appropriate to consider indolent KS as an opportunistic skin disease rather than a
