Diagnosis: Metastatic adenocarcinoma of breast origin.Discussion: • The cells are highly pleomorphic with large nuclei
and nucleoli (Panel A and B). The cytologic features are best appreciated in the cytologic preparation (Panel B).
• The tumor cells form solid sheets. In between the tumor cells are small glands that contain mucin (arrow in the panel on the right).
• The glandular structure are well demonstrated in permanent sections (Panel C). There are also necrosis (Panel D).
• Putting all of these together, the features are most consistent with a metastatic adenocarcarcinoma.
• The patient has a history of breast carcinoma. The positive immunoreactivity of GCDFP-15 confirmed the breast origin. Breast carcinoma are usually negative for TTF-1.
