Metastatic carcinoma to the tongue: a report of two cases and a review of the literature.

Metastatic tumors of the oral cavity are uncommon. Most of them are located in the mandible while only a small percentage are found within the soft tissues. Two cases of metastatic bronchogenic carcinomas to the tongue are described. Review of the literature showed that cancer of the lung was the most common primary lesion that metastasized to the soft tissues of the oral cavity. The base of the tongue was the most prevalent site of metastases to soft tissue within the oral cavity.
