ABSTRACT Introduction: These neoplasms are a group of rare fibroepithelial tumors of the breast, accounting for 0.3-1.0% of breast tumors. Phyllodes tumors are generally classified into benign, borderline, and malignant tumors. Inadequate preoperative diagnosis often leads to local excision with positive margins, which will require surgery to expand margins because of the high probability of recurrence. Objective: Describe the demographic characteristics, diagnosis, treatment, and evolution of patients with tumor phyllodes in the period of March 2012 to March of 2014 in the service of Mastology of the Hospital Central of the Institute of Social Welfare. Patients an methods: Retrospective, observational, descriptive study of consecutive cases. Results: In two years 11 cases of phyllodes tumors were identified, the age range was between 33 to 66 years old, mean 45.9. The tumors had sizes gobetween 4-16 cm, mean 8.3 cm. All underwent core needle biopsy that inform suspected phyllodes in 8 of 11 cases, in 2 cases they reported a fibroadenoma. All underwent exeresis of the tumor where 2 cases were committed and required margins expanding margins, both were the reported as fibroadenoma. All patients have a greater control period to 6 months free of disease. Conclusion: Phyllodes tumors are a group of rare fibroepithelial tumors of the breast, accounting for 0.3-1.0% of all breast tumors ^{(5, 6)}. To distinguish a phyllodes tumor of a fibroadenoma through physical examination is extremely difficult, a core biopsy can accurately diagnose most diseases of the breast ^{(16, 17)}, but may be inconclusive to differentiate a benign fibroadenoma of a phyllodes tumor. ^{(25, 26)}
