Parotid adenocarcinoma metastasis to the breast: A case report

Abstract

Metastatic salivary gland tumors are rare clinical entities of the head and neck. Parotid gland carcinoma with distant metastases heralds a poor prognosis with a median survival of 4.3-7.3 months. The lungs, long bones, liver and brain are the most common sites of metastasis for parotid gland cancer, along with a few reported cases describing metastasis to the ileum, spleen and iliac crest.We present the first case to our knowledge of parotid adenocarcinoma metastasis to the breast.
