This chapter is written for pathology residents, cytopathology fellows, cytotechnologists, and cytopathologists as a resource during rapid on-site assessment of benign or malignant breast lesions. This chapter is intended to provide the reader with key points in order to create differential diagnoses when characteristic cytologic features are seen on fine-needle aspiration smears. Key cytologic features along with clinical and radiologic information are presented, with potential pitfalls and tips as an important resource during on-site evaluation and triaging of these lesions.
