Ultrasound features of male breast cancer are similar to those of female breast cancer. Masses that are taller than wide (antiparallel) and hypoechoic are worrisome. The margins are angulated, microlobulated, or spiculated. [27, 23]

Similar sonographic findings may be observed in gynecomastia or inflammation; therefore, ultrasonography alone is not a reliable method to distinguish male breast cancer from other etiologies. Abscesses, sebaceous cysts, gynecomastia, and fat necrosis may all give false positives.

Evaluation of axillary lymph nodes is important if there is high clinical suspicion for breast cancer. Abnormal lymph nodes with an absent fatty hilum and asymmetric cortical thickness are suspicious for regional metastatic disease.
