Abstract
Myeloid sarcoma (MS) is a rare disease that presents as an extramedullary tumorous mass of immature myeloid precursors. The majority of MS are identified in acute myeloid leukemia (AML) patients and rarely present as a primary isolated MS without AML. In addition, inversion of chromosome 16 [inv(16)] and the CBFβ/MYH11 fusion gene are rarely associated with MS. The current study reports a female patient with an isolated duodenal MS, who developed AML-M4 associated with the CBFβ/MYH11 fusion gene and 48,XX,inv(16),+13,+22. A review of previously reported cases of isolated MS with the CBFβ/MYH11 fusion gene was also performed. Isolated MS with the CBFβ/MYH11 fusion gene was often observed in abdominal lesions, with the intestinal tract being the predominantly involved site. In addition, patients with isolated MS with the CBFβ/MYH11 fusion exhibited a high risk of developing systemic AML. The diagnosis of isolated MS may be particularly challenging and, therefore, determining the optimal standard treatment for isolated MS is required.
