title: Metastatic cystosarcoma phylloides in an adolescent girl: an unusually malignant tumor.
abstract: The first case of metastatic cystosarcoma phylloides in an adolescent is reported. This case also represents the first reported response of this tumor to chemotherapy and irradiation. This tumor showed an unusually rapid rate of cell division probably making it more susceptible to these agents. The importance of an early diagnosis and definitive excision is stressed.
