Invasive Lobular Carcinoma of the Breast: a challenge to the radiologist

Abstract

Invasive lobular carcinoma (ILC) is the second most common histological sub type of breast cancer among women. Its' characteristic immuno-histopathology leads to less conspicuous clinical and radiological features resulting in delayed diagnosis. The difference between ILC and invasive ductal carcinoma (IDC) with respect to risk factors, clinical features, imaging appearances and metastases etc. has been overlooked for many years. In this article, we attempt to review the available literature on ILC emphasizing the difference from IDC.
