| الوصف: | MEIS1-NCOA1/2 fusions are recently described gene rearrangements found in rare sarcomas, mainly involving the genitourinary and gynecologic tracts, with 3 cases reported in the uterine corpus. Although local recurrence was very common, no death has been reported, and some investigators consider these sarcomas low grade. Amplification of genes located at the 12q13-15 locus, especially MDM2 , is the hallmark genetic abnormality in well-differentiated and dedifferentiated liposarcoma of the soft tissue. Some uterine tumors have also been reported to harbor MDM2 amplification, including a proportion of Müllerian adenosarcomas, BCOR fusion-positive high-grade endometrial stromal sarcoma, BCORL1 -altered high-grade endometrial stromal sarcoma, rare JAZF1 fusion-positive low-grade endometrial stromal sarcoma, rare undifferentiated uterine sarcoma, and a single case of MEIS1-NCOA2 fusion sarcoma. Here, we report a case of high-grade MEIS1-NCOA2 fusion uterine sarcoma which also harbored amplification of multiple 12q13-15 genes, including MDM2 , CDK4 , MDM4 , and FRS2 , that exhibited aggressive clinical course leading to patient’s death within 2 yr of the initial diagnosis. To the best of our knowledge, this is the first documented case of fatal MEIS1-NCOA2 fusion uterine sarcoma, and the second case of MEIS1-NCOA2 fusion uterine sarcoma that also harbors MDM2 amplification. |
