Cytologic characteristics of endocrine ductal carcinoma in situ of the breast. A case report.
BACKGROUND
Endocrine ductal carcinoma in situ is a rare form of ductal carcinoma in situ. It is regarded as a distinct subgroup of mammary carcinoma. However, the cytologic features of endocrine ductal carcinoma in situ have not been previously reported.


METHODS
A case of endocrine ductal carcinoma in situ exhibited characteristic cytologic findings on a specimen obtained by the scrape method (stained with hematoxylin and eosin and Diff-Quik).


CONCLUSIONS
The cytologic criteria for endocrine ductal carcinoma in situ are sufficiently distinct and are useful for making the diagnosis on fine needle aspiration.
