Abstract:
OBJECTIVE:Diagnosing myeloid sarcoma remains challenging, and we aimed to provide clinicopathological features to facilitate diagnosis. METHOD:Clinicopathological data from 41 patients with de novo and 31 with secondary myeloid sarcoma were reviewed. RESULTS:Most de novo cases presented with isolated myeloid sarcoma (n = 19) or myeloid sarcoma with concurrent acute myeloid leukemia (n = 15). Most secondary cases presented after acute myeloid leukemia (n = 11), myeloproliferative neoplasm (n = 9), or myelodysplastic syndrome (n = 8). Most frequent localizations were skin and lymph nodes. Immunohistochemistry showed immature and/or aberrant antigenic expression in 29% of de novo and 39% of secondary cases. Most genetic abnormalities were RUNX1-RUNX1T1 (n = 4), CBFB-MYH11 (n = 2), KMT2A-MLLT3 (n = 2), and JAK2 V617F (n = 2) mutations in de novo myeloid sarcoma, and BCR-ABL1 (n = 5) and KMT2A rearrangements (n = 2) in secondary cases. A complex karyotype was seen in 17% of de novo and 39% of secondary cases. Most prevalent treatment was induction chemotherapy followed by consolidation chemotherapy (n = 10) or allogeneic stem cell transplantation (n = 9) for de novo and radiotherapy (n = 11) for secondary cases. CONCLUSION:De novo myeloid sarcoma mostly presented isolated. Lesions were often localized at skin and lymph nodes. Genetic aberrations frequently involved core-binding factor rearrangements in de novo cases and a complex karyotype in secondary cases.
