Metastatic tumors to the oral cavity are rare and they may be localized in the oral soft tissues or jaw bones. Here we present a very unusual incidence of a metastatic adenocarcinoma in the oral cavity originated from lung as first manifestation. Dentists must be aware and suspect such a diagnosis as it mimics odontogenic infections or other benign disorders especially in high-risk patients such as elderly with history of heavy smoking.
