title: Recurrent cystosarcoma phyllodes: a clinicopathologic study of 32 cases.
abstract: A retrospective study was made of recurrent mammary cystosarcoma phyllodes seen at Memorial Sloan-Kettering Cancer Center from 1932 to 1972. Clinicopathologic findings, clinical course, treatment, and survival are described. It is apparent that cystosarcomas may recur and several years may elapse between reucrrences. We found that 18% of the benign and 8% of the malignant cystosarcomas recurred and malignant "transformation" occurred in two of the 28 recurrent benign cystosarcomas.
