[Gingival metastasis: a rare presenting form of renal adenocarcinoma]

Malignant tumors metastasizing to the oral cavity are rare and account for 3.6% to 15.2% for renal adenocarcinoma. These tumors have gross features compatible with benign tumors or inflammatory hyperplasia. Due to the frequency of ulceration and infection of these metastatic tumors, surgical treatment is advocated.
