Abstract
Osseous metaplasia of the breast is considered to be one of the rare breast conditions. It is characterized by the presence of normal bone tissue within the breast. We report a case of benign osseous metaplasia in a 58-year-old woman presenting with mastalgia and mass in the right breast. A lumpectomy was performed. On the pathological examination, the mass was composed completely of benign bone trabeculae with no epithelial component which was confirmed by negativity of immunohistochemistry.

Osseous metaplasia (OM) or “heterotopic bone formation” of the breast is considered to be one of the rare breast conditions; normally the breast stroma is composed of fibrous tissue and fat
The breast stroma contains bone, in which case it called osseous metaplasia that characterized by the presence of normal bone tissue within the breast parenchyma
Summary
Osseous metaplasia (OM) or “heterotopic bone formation” of the breast is considered to be one of the rare breast conditions; normally the breast stroma is composed of fibrous tissue and fat. The breast stroma contains bone, in which case it called osseous metaplasia that characterized by the presence of normal bone tissue within the breast parenchyma. The majority of cases are associated with malignancy and few are described with benign lesions. This is why almost all lesions are suspicious and careful diagnosis should be done for all lesions. We present a rare case of MS which was diagnosed in our laboratory
