Diagnosing Invasive Cystic Hypersecretory Duct Carcinoma of the Breast with Fine Needle Aspiration Cytology

Abstract

The cytologic features of CHC are distinctive and correlate with histology. This was the first presentation of colloidlike secretory material in cytologic material with Papanicolaou stain in such a case. Invasive CHC tends to have aggressive behavior. Cystic hypersecretory hyperplasia coexisted in this case.
