To illustrate imaging findings (mammogram,
MR) in spindle cell lesions of the breast with pathologic correlation. To review diagnostic features and tips for correlation in imaging and pathology.
The term spindle cell lesion refers to a broad group of entities ranging from reactive processes to aggressive malignanttumours,
which arecomposed of cells with the typical morphological apperance of spindle cells. Their origin is most frequently mammary epithelial cells with metaplastic changes to spindle mesenchymal-like cells.
But also myoepithelial cells may proliferate showing different morphological appearances,
including spindle cell.Proliferatingintralobularand interlobular mammary...

Practical approach classification Fig. 2 . 1.Bland-looking breast spindle cell lesions. Reactive and neoplastic mesenchymal and epithelial/myoepithelial lesions that can be classified as: 1.1. Lesions of mesenchymal fibroblastic/myofibroblastic origin. 1.1.1.

Different spindle cell lesions may be found either benign or malignant and radiologists should be familiar with imaging findings in order to recognize them. Always consider the possibility of metaplastic carcinoma,
the most important differential diagnosis.
