Dedifferentiated endometrial carcinoma: an ongoing diagnostic dilemma

Abstract

Tumours of uterine corpus are the most common gynaecological malignancies. The clinicopathological features of most of these tumours are well understood; however, dedifferentiated endometrial carcinoma still requires a lot of research to establish adequate management guidelines. The entity was first described in 2006 and is an aggressive tumour with poor prognosis. We present two cases of this tumour with a literature review, emphasising morphologic and immunohistochemical features that may help in the differential diagnosis.
