title: Cytologic interpretation of fine-needle aspiration biopsies from clinically occult breast masses.
abstract: Fine-needle aspiration biopsy (FNAB) was performed on 39 occult breast masses of soft tissue density using standard mammographic guidance. All malignant tumors were diagnosed as either positive or suspicious for carcinoma, and there were no false-positive or false-suspicious diagnoses. These excellent results can be attributed to accurate cytologic interpretation based on consideration of problems unique to these lesions and the sampling method, such as scantier cellularity, potentially less confidence in needle placement, and the nature of the occult mass itself. The team approach between pathologist, radiologist, and clinician is emphasized.
