Abstract：Objective: To study the ultrasonic characteristics and clinical features of the breast phyllode tumor(PTB). Methods: Clinical and imaging findings were retrospectively reviewed in 10 cases with 10 phyllode tumors identified at preoperative ultrasonography. Results: All patients were female, age ranged from 21 to 59 years old, each of them had a history ranged from 1 week to 5 years. Painless breast lump was the common presentation. On clinical examination, all lumps were firm and mobile. Ultrasonography display 10 lumps and the upper outer quadrant was the most commonly involved site(7/10). The ultrasonic characteristics of images were divided into three types, their shape including lobulated(n=6), round and oval(n=3), irregular in shape(n=1, as mixed echoes of cystic and solid). The tumor diameter varied between 1.5cm and 9.5cm. According to the histologic criteria of WHO, of all the cases, 6 were benign PTB, 2 cases were borderline and 2 cases were malignant PTB. Most of the borderline and malignant PTB showed blood flow grade II~III. Endotumoral calcifications and secondary sign of malignancy were absent. Conclusion: Although many of the phyllode tumors are indistinguishable from fibroadenoma on the basis of clinical and ultrasonic characteristics, in large breast tumors with rapid growth, and show typical ultrasonic characteristics, the tentative diagnosis of phyllodes tumors should be considered.
