title: [A case report of a metaplastic carcinoma of the breast diagnosed by the preoperative needle biopsy].
abstract: A case of the metaplastic carcinoma, a rare type of the breast cancer, was reported. A 49-year-old woman noticed the left breast lump. Ultrasonography revealed a well circumscribed hypoechoic mass measuring 3 cm in diameter. The preoperative needle biopsy showed the invasive carcinoma with chondrometaplasia. The modified radical mastectomy along with the lymph node dissection was performed. There have been few reports of the metaplastic breast carcinoma diagnosed preoperatively.
