Clinical and mammographic characteristics of phyllodes tumor

Objective:To investigate the characteristics of clinical and mammographic findings of breast phyllodes tumors.Methods: The data of 5 involved cases confirmed both postoperatively and pathologically were analyzed retrospectively.Results: The five patients were all females aged between 30 and 50 with an average of 40.3 years old.Each patient visited the doctor because of unexpected detection of indolent mass in breast and the symptom progressed from 1 month to 10 years.Rapid growth of the mass was seen currently in 3 cases.On the physical examination,the lesions were firm but mobile,with smooth surface,no tenderness and sharply defined outline.The mammographic findings suggested that the four masses were sit mostly on the upper outer quadrant in anatomic structure(66.7%), sized in diameter between 2.0 and 4.5 cm with an average of 3.6 cm.All lumps were high density or equal density,shaped lobulately(n=3) or ovally(n=1). Only one case demonstrated local high density but with no shadow zone.The mass in four cases were well-defined,in which three showed a clear partial halo.Conclusion: In older female cases,provided that the mass in breast grow rapidly in short period,even though the mass is painless with mammographic findings of seemingly benign,it may be considered as phyllodes tumor,especially that of lobulately shaped.
