Metastasis of pulmonary adenocarcinoma to the palatine tonsil

Lung cancer rarely metastasizes to the palatine tonsil. There have only been a few cases that have reported on palatine tonsillar metastases of pulmonary adenocarcinoma. In the majority of these cases the primary diagnosis is a small cell lung cancer. The present case report resents an unusual case of a 66-year-old woman with a multiple metastasized lung adenocarcinoma, which was finally detected by tonsillectomy. The present case report and review of the literature revealed the importance of complete and systematic tumor staging, including the examination of the oral cavity in case of lung cancer and that the evident tentative diagnosis is not always the right one.
