Inflammatory pseudotumor of the breast: case report and literature review.

Inflammatory pseudotumor (IP) is a benign lesion that can affect any tissue in the body and which may be confused clinically and in imaging for malignancy. Despite the widespread performance of breast biopsy, the finding of inflammatory pseudotumor of the breast is exceedingly rare. Excision of the tumor is the treatment of choice, but there is a relatively high rate of recurrence. The aim of this report is to describe the clinical, imaging, and pathologic features in a case of breast IP, the first reported case in a postpartum woman still nursing her infant.
