Metastatic lung malignancy to mandibular gingiva.

ABSTRACT

Metastatic tumors of oral cavity are uncommon and may occur in oral soft tissues or jaw bones. Because of their rarity, metastasis to oral cavity are challenging to diagnose and difficult to treat. They often have vague symptoms that mimic dental infections. These lesions generally show poorly differentiated histopathologic picture and have poor prognosis. We reported a case of a 40-year-old male patient of metastatic lesion to the oral cavity and brain with primary tumor, diagnosed as an undifferentiated epithelial malignancy of lung.
