Tumor filodes mamario: una revisión clinicopatológica de 14 casos / Phyllodes tumor of the breast: clinical pathological review of 14 cases

ABSTRACT

We report a retrospective analysis of 14 female patients, aged 20 to 62 years old, with phyllodes tumors of the breast. The tumors were located in the right breast in nine patients and their diameter ranged from 2.5 to 28 cm. Six mammographies and six needle cytological examination were performed and aided very little to the diagnosis. The preoperative diagnosis was correct in five patients and the principal differential diagnosis was fibroadenoma. Eight patients were subjected to tumorectomy, three to simple mastectomy, one to a clining mastectomy; one to a modified radical mastectomy and one to a subcutaneous mastectomy. The anatomopathologic study disclosed an increased stromal growth in 2 patients and increased stromal cellularity in six cases. Only one case had more than five mitoses per microscopic field. Phyllodes tumors are infrequent, their diagnosis requires a high degree of clinical suspicion and they have a benign biological behaviour
