Mucinous Carcinoma of the Breast: MRI Features of Pure and Mixed Forms with Histopathologic Correlation

Abstract

Hypercellular pure mucinous tumors exhibit strong early enhancement and may be difficult to differentiate from mixed mucinous tumors. The distinction between the pure and mixed forms of mucinous carcinoma is important because mixed mucinous carcinoma more frequently undergoes lymph node metastasis and has a poorer prognosis than does pure mucinous carcinoma.
