Following publication of the original article [1], it has been brought to our attention that an incorrect Sequenom MassArray trace and an incorrect nomenclature were used to represent the PIK3CA p.E545A mutation in Fig. 2b. The correct Fig. 2b is shown in this erratum. The authors apologize for the confusion.

a Mutational profiling of the 15 cases profiled through a hotspot multigene mutational custom panel, including 164 hotspot regions of AKT1, APC, BRAF, CTNNB1, KIT, KRAS, NRAS, PDGFRA, PIK3CA, PTEN and TP53 genes. In red are the samples showing a different mutational landscape in comparison to the other matched samples (scale bars = 100 µm). b Representative Sequenom MassArray output profiles for KRAS c.436G> A (p.A146T), PIK3CA c.1634A>C (p.E545A), BRAF c1799T>A (p.V600E) and NRAS c.35G>A (p.G12D) mutations.
