1. Endometrial cancer. A, B: Long-axis images of a polypoid mass surrounded by a thin sliver of intraluminal fluid. This tumor occupied the entire uterine lumen and was found to be an endometrioid cancer. C, D: Invasive endometrial cancer extending to uterine serosa in the fundal region. D: Picture of gross specimen showing tumor extending to serosa. E: Noninvasive endometrial cancer appearing as bulky tumor that markedly distends the uterine lumen. Because the inner hypoechoic myometrium was seen to be intact on transvaginal sonography, this was correctly determined to be noninvasive. F: Invasive endometrial cancer. As opposed to the patient shown in (E) there is disruption of the junctional zone (arrow) in this invasive tumor. G: Focally invasive endometrial cancer in a patient on hormone replacement therapy. There is a "tongue" of echogenic tissue disrupting the inner myometrium, indicating that this is locally invasive.
