p53 immunohistochemical analysis of fusion‐positive uterine sarcomas

Aims Uterine sarcomas can be grouped into tumours with pathognomonic genetic fusions such as low‐grade endometrial stromal sarcoma (LGESS), high‐grade endometrial stromal sarcoma (HGESS), and inflammatory myofibroblastic tumour (IMT), and tumours lacking genetic fusions such as leiomyosarcoma (LMS) and undifferentiated uterine sarcoma (UUS). Members of the latter group frequently harbour TP53 mutations. The aim of this study was to evaluate TP53...
