SIX CASES OF CYSTOSARCOMA PHYLLODES

Cystosarcoma phyllodes is occasionally encountered, but its diagnosis is likely to depend on histological examination after its removal. Only a few comprehensive studies concerning its noninvasive diagnosis have been reported. Therefore, focal findings in the breast and ultrasound findings of tumors were investiaged in six cases of cystosarcoma phillodes. The sizes of the tumors were 3 to 19cm in diameter, and one of them had extensive skin ulceration, which is rare, but differential diagnosis from other malignant diseases with skin ulceration is quite important. Histological examinations revelaed benign cystosarcoma phillodes in all cases which coincided with the findings of the ultrasound examination. The characteristic findings of ultrasound examination were solid and sometimes cystic patterns with smooth and well defined tumor margins with no acoustic attenuation. Cystosarcoma phillodes can be diagnosed preoperatively with the combination of careful observation of its clinical manifestations and the use of ultrasound examination.
