Neurofibromas are common benign tumors and can originate from any nerve tissue in the body. A solitary neurofibroma in breast parenchyma has rarely been reported, however. We report a neurofibroma originating from breast parenchyma in a 61-year old woman. On mammography, the mass appeared as a well marginated and circumscribed mass, suggesting a benign tumor, and after excisional biopsy, was pathologically proven to be a neurofibroma.
