Abstract
It is very unusual that non-invasive ductal carcinoma coexists with Pyllodes tumor. A 62-year-old woman was admitted to the hospital because of a large mass in the left breast. Simple mastectomy was performed with a diagnosis of phyllodes tumor and intraoperative frozen section diagnosis confirmed “Phyllodes tumor, borderline”. But, permanent section revealed the coexistence of non-invasive ductal carcinoma with Phyllodes tumor Axillary lymph nodes dissection was added. No recurrence or metastasis has been observed over the post operative period of 30 months. Though it is rare, phyllodes tumor of the breast can be associated with breast carcinoma like in this case and we have to entertain this possibility in the treatment of phyllodes tumor.
