AI Article Synopsis

  • Malignant tumors in the parotid gland are rare, and this case highlights a unique instance of breast cancer metastasizing to that gland.
  • The case involves a 74-year-old woman diagnosed with lobular carcinoma of the left breast four years before, undergoing surgery and radiotherapy, but refusing chemotherapy.
  • Three years later, she developed a nodular change at the surgical site and facial paralysis due to metastasis in the right parotid gland, emphasizing the need to consider breast cancer as a possible source in similar cases.

Article Abstract

Purpose: 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.
