ABSTRACT

Introduction: Phyllodes tumor is a fibroepithelial neoplasm histologically very similar to fibroadenoma. Its frequency is 1% of mammary lesions; its greatest incidence is between the fourth and sixth decades of life, as a rule these are tumors larger than 10 cm. 75% of cases are benign, 15-18% are malignant and 8% are borderline. In general, it is estimated that there may be a 10% recurrence. The wide resection is the treatment of choice, having to perform reconstruction of the surgical defect, preferably with advances of abdominothoracic flaps or rotation of the broad dorsal. Among the risk factors for recurrence, the size of the initial lesion stands out, especially when they are tumors larger than 15 cm. It has been described that patients who present recurrences may turn to malignancy or to different histological strains different from the initially benign tumor. Clinical case: A 47-year-old woman with no personal pathological history who, one year before her consultation, begins with a slow-growing tumor in the left breast. A trucut biopsy is performed with a report of benign phyllodes tumor, treated with a simple mastectomy. Two months later it presents voluminous recurrence, for which ample resection is made, including both pectorals and part of the wide dorsal, reason why it is reconstructed with abdominothoracic flap, transoperative of malignant phyllodes tumor, with negative edges and negative site. Conclusion: Tumor phyllodes corresponds to 1% of mammary tumors; it is rare and recurrent, especially if they are bigger than 15 cm; in addition, they can change their histological lineage. Its treatment is wide resection with negative edges to reduce recurrences.
