Abstract: Breast cancer metastatic to parotid gland is a very rare condition which tend to confer poor prognosis and challenging approaches. Oligometastatic breast cancer is usually defined as advanced breast cancer with less or equal than 5 metastatic lesions. We report a case of oligometastatic HER-2 breast cancer to parotid gland and lymph nodes which presented with left hemifacial swelling with erythema and enlargement of cervical and axillary lymph nodes. After 6 cycles of Docetaxel plus Trastuzumab the patient had complete response that was complemented with posterior surgical removal of primary tumor followed by radiotherapy directed to plastron, left supraclavicular and cervical drainage. The patient is still on Trastuzumab therapy and is free of disease in the last two years. We discuss the presentation and approach of a patient with metastatic breast cancer to parotid gland in the oligometastatic scenario.
