Abstract
A 54-year-old woman who had been administered psychotropic drugs for asyndesis since 1977 was seen at the hospital because of a left breast tumor on January 17,2004. On palpation an elastic-hard, demarcated, and well-movable tumor with a smooth surface was present in the CA area of the left breast. Benign phyllodes tumor was diagnosed by fine needle biopsy cytology, and a total mastectomy was performed on March 8. Histopathologically the main part of the tumor was borderline phyllodes tumor, and in its deep part a scirrhous carcinoma was present with intraductally invading foci close to the tumor.
It is extremely rare that a phyllodes tumor and breast cancer synchronously occur in the ipsila t eral breast, so that this case is presented here, together with a review of the literature.
