PHYLLODES TUMOR
Phyllodes tumor of the breast is a rare fibroepithelial breast tumor. Its incidence is 2-3%. Phyllodes tumors are classified as benign, borderline or malignant. It is often benign and rarely appears in its malignant form. Although it is most often seen at ages 35-55, malignant phyllodes tumors are seen at older ages.
Since a phyllodes tumor has a much higher growth rate than fibroadenomas, it begins to take up space inside the breast at an early stage. Imaging methods such as breast ultrasound, mammography and breast MRI, and in many cases biopsy, are insufficient in the differential diagnosis. The definitive diagnosis is made by pathological evaluation after the mass has been completely removed.
The treatment of phyllodes tumors is surgical removal of the mass together with at least 1 cm of surrounding breast tissue. Regional recurrence in the breast often occurs. In giant phyllodes tumors, removal of the whole breast may be healthier. In this case the breast is rebuilt with a silicone prosthesis. There is generally no spread to the armpit lymph nodes; surgical intervention for them is not recommended.
Benign phyllodes tumors are treated surgically, while in malignant phyllodes tumors radiotherapy to the chest wall may be applied after surgery. Close follow-up after surgery is important for regional recurrence.
