Abstract
We report the case of a 27-year-old female with intraparenchymal leiomyoma of the breast. This case is interesting not only because intraparenchymal leiomyoma of the breast is a rare benign non-epithelial tumor, but also because it is never found in women at such an early age. We explain all the aspects of this case in this report with its radiologic, histopathologic and immunohistochemical findings.
