Immunohistochemistry performed on both stomach and ileum showed diffuse and strong positivity for CD34, MPO Ckit, MiB1 being 70% and negativity for CD3, CD20, and CD10 (Figures 2 and 3), thus making a diagnosis of extramedullary myeloid tumour or involvement by AML. This evidence concerns the gene MME and acute myeloid leukemia.
