A Literature Review in Renal Carcinoma Metastasis to the Oral Mucosa and a New Report of an Epulis-Like Metastasis

摘要

Metastatic tumors represent 1% of the oral malignancies most often originating from the breast, lungs, and kidneys.Concerning the oral cavity, metastases are usually located in the posterior region of the mandible. Metastatic lesions to the oral soft tissues and gingiva have also been reported.Metastatic tumors to the gingiva are extremely rare. Tsianos et al reviewed 14 well-documented cases of gingival metastasis without involvement of the underlying jaw bone and presented another case of frank malignant metastasis to the gingiva. Of these cases, 13 were carcinomas and 2 were sarcomas. The maxillary gingiva was involved in 5 cases, the mandibular gingiva in 7, and both of them in 3. The first case of hypernephroma metastasized to the gingiva was reported in 1928 by Branch and Norton
