[Cytological and histological studies in stereotactic punctures of non-palpable solid breast lesions]

Cytologic aspiration and core biopsy were performed on 50 nonpalpable breast lesions by using a stereotactic localization technique. Cytologic and histologic results were correlated with mammographic findings and therapeutic decisions were based on the results of both procedures. Representative material was obtained in 100% of the lesions. The sensitivity was 90% and specificity was 97.5%. The predictive values were high except for the predictive value of a negative histologic finding in a suspicious cluster of microcalcifications (50%).
