Spindle Cell Lesions of the Breast

 

Pure spindle cell lesions of the breast are both rare and diagnostically challenging. This presentation will compare the clinical, radiologic and immunohistologic features of malignant and benign spindle cell lesions of the breast, including some case examples where the distinction is particularly difficult and important.

Originally presented on February 10, 2020, in Park City, Utah.
