Metastatic patterns of invasive lobular versus invasive ductal carcinoma of the breast.

Abstract

The metastatic patterns of lobular and ductal carcinoma of the breast are different, with gastrointestinal system, gynecologic organ, and peritoneum-retroperitoneum metastases markedly more prevalent in lobular carcinoma. Physicians should be aware of these different metastatic patterns of lobular and ductal carcinoma of the breast.
