Patients affected by monoclonal gammopathy of undetermined significance (MGUS) very rarely develop a myelodysplastic syndrome (MDS). However, it was also demonstrated that MGUS patients had a significantly increased risk of developing MDS compared to the general population. We report a case of 5q-syndrome following a MGUS IgMk with mutation of MYD88 L256P. To our knowledge, this is the first case of del(5q) MDS following MGUS IgMk with the MYD88 L256P mutation in which there is coexistence of the markers of the two clonal diseases, but as an expression of distinct pathological features.

Abstract
Patients affected by monoclonal gammopathy of undetermined significance (MGUS) very rarely develop a myelodysplastic syndrome (MDS). However, it was also demonstrated that MGUS patients had a significantly increased risk of developing MDS compared to the general population. We report a case of 5q-syndrome following a MGUS IgMk with mutation of MYD88 L256P. To our knowledge, this is the first case of del(5q) MDS following MGUS IgMk with the MYD88 L256P mutation in which there is coexistence of the markers of the two clonal diseases, but as an expression of distinct pathological features.File in questo prodotto:
