Abstract: The objective of the current study was to determine the accuracy of radiological and cytological diagnoses of intracystic and papillary lesions in distinguishing between true papillary benign and malignant lesions. Seventy cytological reports of intracystic proliferations were selected from our cytopathological database at the Breast Health Corporation, Budapest, Hungary, dating back to the last 7 years. Retrospective analysis of the diagnostic approaches – mammography, ultrasonography, clinical examination and cytology – was performed in selected cases. The results of imaging and cytological examination are routinely reported on a categorical scale ranging from 1 to 5. 44 patients underwent surgical excision: histology showed benign lesions in 21 and malignant lesions in 23 cases. Twelve patients, who did not undergo biopsy and presented a stable disease at follow-ups, were also included in the group of benign lesion. Fifteen patients were not available for follow-up. Concerning the total investigated cases the mean categorical values of mammography, ultrasonography and cytology were 2.24, 2.78 and 3.05 respectively. The malignant and benign groups significantly differ from each other concerning the mean age of the patients (p=0.0216), the distribution of the coded mammographical results (p= 0.0171) the cytological results (p=0.0001), and average tumor size measured on mammogram images (p=0.0199). The two group does not significantly differ over the distribution of mammographical density patterns (p=0.1075), radiomorphological appearance (p=0.1101), average tumor size measured on ultrasonography (p=0.2665), and patient complaints (p=0.2634). The evaluation of ultrasonography shows borderline significance (Pearson Chi-square test: p=0.0616, M-L Chi-square test: p=0.0404) between the malignant and benign groups. Differential diagnosis between malignant and benign intracystic and papillary lesions is feasible using common radiological diagnostics. However, more efficient teamwork is needed with the cooperation of a well-trained cytologist and radiologist, who are able to produce precise images of the lesions, and guides the aspiration of the adequate samples for cytology, which is the most valuable examination.
