Introduction: The phyllodes tumor (PT) of the breast is a rare disease of unknown origin. Despite its classification into benign, borderline and malignant, their behavior tends to he uncertain. Because of this, treatment remains controversial. Objective: To describe the management of the FT in breast pathology unit of our hospital and their outcomes. Material and Methods: We retrospectively reviewed the files of the patients with PT, operated in our hospital between 2001 and 2008. We analyzed the clinical characteristics, diagnostic studies, treatment and outcomes. Results: During this period 12 patients were operated. The average age was 42 +/- 15.2 years (16-64) and usually the form of presentation was painless palpable nodule. Both mammography and ultrasound were unable to suggest the diagnosis. Eight patients had core biopsy, which revealed the diagnosis of PT in 5, while in the other 3 was fibroadenoma. All patients underwent a partial mastectomy. The biopsy showed six benign, two borderline and two malignant PT. The latter two patients received adjuvant radiotherapy. At the end of this study, 2 patients had relapsed at 12 and 30 months (borderline and benign, respectively). There were no cases of lymphatic or distant metastases. Conclusions: The PT has a low frequency of presentation and preoperative diagnosis is difficult, so we recommend a core biopsy, but it can confuse with fibroadenoma. The management with partial mastectomy and negative borders had a recurrence rate of 18% in this series.
