Invasive Cribriform Carcinoma of the Breast: A Case Report

tinct histologic type of invasive carcinoma that was first described by Page et al. in 1983 (1) and is characterized by a cribriform histologic pattern in the majority of its invasive component (1). Cribriform carcinoma is a welldifferentiated variant of invasive ductal carcinoma and has a relatively favorable prognosis and low frequency of axillary nodal metastases (2). To our knowledge, the radiologic findings of invasive cribriform carcinoma of the breast are limited. MR imaging findings have not been previously described and there were highly suspicious findings of the masses on mammography and sonography in previous reports (3, 4). We report a case of invasive cribriform carcinoma of the breast with sonographic findings indicating a low suspicion for malignancy and MR imaging findings.
