Cytology is not like mucinous ca. Mucinous ca show extracelluar mucin and hypocellular smears. Lobular ca is differential dx in cytology slides.
Based on H&E, it looks like a invasice ductal carcinoma with apocrine future. DCIS may be present also. If all tumor cells share same feature, you can call apocrine carcinoma as 有福不在忙 mentioned. Apocrine ca is a type of ductal ca and the prognosis is the similar to ductal ca. Generally I call invasive ductal ca with apocrine feature.
If you doubt lobular carcinoma, you can do a stain, e-cadherine.
