Metastatic Lung Carcinoma Involving the Maxillary Gingiva.

Metastatic spread of malignant tumors to the oral soft tissue is rare and account for 0.1% of all oral malignancies. Metastatic spread to the oral soft tissue can present as dental infections, which in turn can create a diagnostic challenge. Metastasis to the oral soft tissue from lung cancer is a rare situation. Here we describe a 52 year-old male patient treated initially with antibiotics for presumed oral abscess, who later was found to have metastatic lung cancer involving the maxillary gingiva.
