History

Phyllodes tumors generally manifest as larger masses and display rapid growth. A small mass may rapidly increase in size in the few weeks before the patient seeks medical attention. Tumors rarely involve the nipple-areola complex or ulcerate to the skin. Patients with metastases may present with such symptoms as dyspnea, fatigue, and bone pain.

Physical Examination

A firm, mobile, well-circumscribed, nontender breast mass is appreciated. Curiously, phyllodes tumors tend to involve the left breast more commonly than the right. Overlying skin may display a shiny appearance and be translucent enough to reveal underlying breast veins. A very large phyllodes tumor may erode through overlying skin and present as an external fungating breast mass. [11]  More typically, physical findings (ie, the occurrence of mobile masses with distinct borders) are similar to those of fibroadenoma. [7]
