Background:
Phyllodes tumor represents one of the fibroepithelial breast neoplasms that accounts for 0.3% to 1% of the breast tumors.
Objective:
To describe a case series of patients with phyllodes tumor diagnosis.
Material And Methods:
We retrospectively reviewed the medical records of patients that had confirmed histological phyllodes tumor collected over a period of ten years.
Results:
The incidence was 0.8%, 12.5% of cases corresponded to malignant phyllodes. The average age was 35 years (range 14-50 years); the most frequent site of localization was the superior and external quadrant of the breast; the average tumoral size by image studies (ultrasound or mastography) and by direct measurement was 61 mm (13-150 mm) and 77 mm (30-300 mm), respectively. One case coexisted with pregnancy.
Conclusions:
It is a rare neoplasm, andthe clinician must be aware of its timely diagnosis and treatment, if not some cases will develop breast deformity and some others will be borderline or malignant.
