Abstract

We herein report a case of phyllodes tumor occurring in the right breast of an 11-year-old girl. She first noticed a mass in the right breast at the age of 11 years. She consulted our hospital due to an ongoing increase in the size of mass three months after the first notice of the mass. The well margined mass of 12×12×9cm in size was elastic and soft and occupied the whole right breast. Fine needle aspiration cytology demonstrated component of epithelial cells without any evidence of malignancy. CEA and CA15-3 were within normal range. Because the tumor was diagnosed as a benign tumor such as a fibroadenoma or phyllodes tumor by the preoperative imaging studies with CT and MRI, a simple tumor extirpation was performed through an inframammary incision leaving as much breast gland as possible. The postoperative histological examination confirmed the diagnosis of a benign phyllodes tumor. The postoperative progress is uneventful without a local recurrence in a follow-up of three years, even though the development of the remaining breast gland is still not compensated.
