Fine needle aspiration biopsy cytology of phyllodes tumour and fibroadenoma: A cytomorphological study of 104 cases.

The results of this study indicate that in all of the cytological features assessed for PT and FA, no single cytological feature was found to be statistically significant in identifying PT across all observers. This reflects the overlap of cytological features seen in these lesions. FNAB cytology cannot reliably distinguish FA and PT.
