Unusual sonographic appearance of breast cancer metastasisto the pectoralis muscle

초록

Breast cancer is one of the most common malignancies in women. It frequentlymetastasizes to the lungs, liver, and bone. Breast cancer metastasis to skeletal mus-cles is rare. Chest wall recurrence in patients that have undergone mastectomy is themost frequent form of local recurrence, and it is generally accompanied by nodulesor masses on the chest wall. Here, we describe a case of the unusual appearance ofinvasive lobular cancer metastasis to the pectoral muscles without discrete nodulesor masses in a patient who had undergone mastectomy 12 years ago.
