Abstract

Objective: This study aimed to describe the mammographic characteristics of female patients diagnosed with breast carcinoma in situ. Methods: A cross-sectional descriptive study was conducted on 139 patients with DCIS at National Cancer Hospital from September 2019 to October 2024. Mammographic findings were described using the American College of Radiology Breast Imaging Reporting and Data System (BI-RADS), 5th edition (2013), and correlated with postoperative histopathological results. Results: The mean age of patients was 52 ± 11.4 years. DCIS accounted for 96.4% of cases, with high nuclear grade observed in 56%. Mammographic findings predominantly showed microcalcifications (77.7%), with pleomorphic (50.9%) and amorphous (23.1%) morphologies being the most common. These microcalcifications were typically distributed in segmental (46.3%) or grouped (39.8%) patterns. Mass lesions and architectural distortions were less frequently observed. Conclusion: The findings highlight the critical role of mammography in the early detection and diagnostic orientation of breast carcinoma in situ, which typically presents as pleomorphic or amorphous microcalcifications in segmental or grouped distributions.
