    Uterine Myxoid Inflammatory Myofibroblastic Sarcoma (MIMS) Harboring Pathogenic KRAS Mutations and Expressing ER, PR, and CD10. (PubMed, Int J Gynecol Pathol)
    No gene fusions in PDGFRA/B, JAK1, PML, ALK, ROS1, PLAG1, or any other gene were identified by whole transcriptomic RNA sequencing. Given its deceptively bland appearance and its propensity, at least in the uterus, to express both CD10 and ER with only focal SMA expression, MIMS can be mistaken for an endometrial stromal tumor, an ALK and ROS1-negative uterine inflammatory myofibroblastic tumor, or other cytologically bland fusion-driven uterine mesenchymal neoplasms.

    Cancer mutations in RAD51 and its paralogues. (PubMed, PLoS One)
    A comparison of mutations reported on COSMIC with those reported on ClinVar revealed that many mutations primarily in RAD51C and RAD51D are also hereditary. Thus, it appears that an apparent low level of RAD51 mutations in cancer cells is compensated by an increase in paralogues mutations.

    Characteristics of uterine leiomyosarcoma: a clinicopathological and molecular genetic analysis of twenty-four cases (PubMed, Zhonghua Bing Li Xue Za Zhi)
    Secondary morphological changes in uterine leiomyosarcomas associated with hormone therapy pose significant diagnostic challenges. Next generation sequencing can provide valuable evidence for the diagnosis of morphologically challenging cases of leiomyosarcoma in clinical practice.
