Mammary fibromatosis.

Abstract

This article illustrates the imaging findings that have pathologic correlation and the clinical presentation of mammary fibromatosis. Mammary fibromatosis is a rare, benign, nonmetastasizing stromal tumor. It presents clinically and radiologically as a palpable, spiculated, and locally invasive tumor that is suspicious for malignancy. MRI is ideal for evaluation of chest wall involvement. Although histologically benign, the tumor is locally aggressive and has significant recurrence rates. On occasion, recurrence may require radical surgery.
