Abstract
ER-/PR+ is a controversial subtype and is not formally recognised as molecular subtype of breast carcinoma. Few studies concluded that this subtype does not exist and is due to technical errors, however, in contrast others consider it to be distinct entity with different response to therapy and clinical outcome. It is also essential to know whether this subtype shows any distinct histomorphological features or prognosis.Therefore, the present two cases of controversial subtype ER-/PR+ breast cancer is being reported with both the cases showing neuroendocrinal differentiation.
期刊介绍：
The recent expansion of work in the field of breast cancer inevitably will hasten discoveries that will have impact on patient outcome. The breadth of this research that spans basic science, clinical medicine, epidemiology, and public policy poses difficulties for investigators. Not only is it necessary to be facile in comprehending ideas from many disciplines, but also important to understand the public implications of these discoveries. Breast Disease publishes review issues devoted to an in-depth analysis of the scientific and public implications of recent research on a specific problem in breast cancer. Thus, the reviews will not only discuss recent discoveries but will also reflect on their impact in breast cancer research or clinical management.
