[Parotid metastases: value of imaging. Review of the literature, apropos of 4 cases].
Parotid gland is a very unusual site of metastasis. Four proven cases are described. The tumor was occult in three cases out of four. In one case, an extra neck primitive tumor was suspected. Two kinds of metastases are described: firstly, metastases within the salivary gland with look like pleomorphic adenoma and are secondary to hematogenous spread; secondly, lymph node metastasis (two cases). Their diagnosis appear easier as they are not usually completely surrounded by parenchyma. They can reveal either occult head and neck tumor or visceral tumor.
