title: Contralateral metastasis of parotid gland in advanced breast cancer with peripheral facial paralysis.
abstract: OBJECTIVE
  Malignant tumors of the parotid gland are very rare. Until now there have only been a few reported cases of patients with distant metastasis of breast cancer in the parotid gland. This case shows the rarity of the disease.
  
  
  METHODS
  This case is about a 74-year-old woman with an invasive lobular carcinoma of the left breast. The initial diagnosis was made four years ago. The operation which was done was a quadrantectomy and axillary lymph node dissection. It was followed by radiotherapy of the breast. The recommended chemotherapy was declined by the patient.
  
  
  RESULTS
  Three years after the initial diagnosis of lobular invasive breast cancer a nodular change in the cicatrice of the mastectomy occurred. The patient also had a contralateral peripheral facial paralysis, caused by a distant metastasis in the right parotid gland.
  
  
  CONCLUSIONS
  When there is a tumor in the parotid gland and a histological classified adenocarcinoma is found, the differential diagnosis of breast cancer metastasis should be considered.
