Encapsulated papillary carcinoma is a very rare form of breast cancer that accounts for 1-2% of all cancerous breast tumors. It is a cancer that usually presents in postmenopausal females, but can be found in men as well. It is a slow growing cancer with a favorable prognosis, and has a 5% local recurrence rate. However, it is still a malignant cancer that needs to be treated as quickly as possible. Ultrasound is a diagnostic imaging tool that can be implemented when a patient has a suspicious area seen on a routine mammogram. This case study covers how ultrasound can be used to diagnose encapsulated papillary carcinoma in men specifically. Male breast cancer needs to be addressed more often, and ultrasound is a method that can be implemented to prevent and diagnose breast cancer in men.
