JAZF1 rearrangements are typically characteristic of low-grade lesions, high-grade lesions usually harbor YWHAE alterations, and undifferentiated uterine sarcomas commonly present with complex karyotypes. We report a case of an endometrial stromal sarcoma with a JAZF1 gene rearrangement by fluorescence in situ hybridization and high-grade cytology presenting as cardiac and colonic metastases, in a patient with a remote history of hysterectomy for to “leiomyomas.” From the Department of Pathology and Laboratory Medicine, Hospital of the University of Pennsylvania, Philadelphia, PA.
