Aims & Objective: To study breast masses with the help of ultrasonography and to find correlation between USG and histopathology regarding same.

Materials and Methods: In the present study we observed 100 patients with breast lump came to OPD at MGM Medical College & Hospital, Aurangabad, Maharashtra, India. Study duration was from June 2018 to June 2020. The lumps in the breast were evaluated by Ultrasonography. The lesions were also evaluated pathologically and classified using the Van Nuys classification system. Statistical comparisons were made using Fisher's exact test.

Results: 18 out of the 100 cases were circumscribed masses. 58 out of 100 tumors were recognized with halo using Ultrasonography (USG). 52 out of these 58 tumors with halo were defined as ‘histopathologic halo’. About 59.7% of the tumors in which internal echoes were equal / heterogeneous histopathologically were associated with poor collagenized stroma and heterogenous intratumoral structure. The ratio of carcinoma cells to stroma was 3:1–1:3.

Conclusion: Ultrasonographic (USG) cannot define the extension of carcinoma preoperatively, correlating US findings with histopathologic features of carcinoma cells can determine the extension of carcinoma.
