dc.descriptionNon-epithelial tumors of the breast are extremely rare and have an incidence of less than 1%. The most common non-epithelial breast tumor is the phyllodes tumor (PT), which accounts for 61%. Primary osteosarcomas of the breast contribute up to only 12.5% of all breast sarcomas. In young females, osteosarcomas are extremely rare, especially in those without a previous history of primary bone osteosarcoma. A case of a 16-year old female with primary osteosarcoma of the breast (POB) with extensive chondroid matrix involving the left breast is herein presented. This report describes a 16-year old female with neither a previous history of bone osteosarcoma nor family history of breast cancer who was diagnosed with a primary chondroblastic osteosarcoma of the left breast. The mass was shining, warm, firm, and slightly fixed. The excisional biopsy showed a large tumor measuring 11x9x7 cm which was encapsulated, grayish-white, and nodular. Primary osteosarcomas of the breast carry a poor prognosis by being triple negative and because of being the rarest tumors, they pose a challenge in managing the patients due to lack of established treatment modalities.
