RESUMO
Metastases from malignant tumors in the oral cavity are rare and comprise approximately 1% of all oral neoplasms, being more frequent in the jaws than in the soft tissues. The presentation of a gingival metastasis as the first manifestation of a primary tumor in the oral cavity is extremely rare. The objective of this review is to update the diagnosis and management of oral metastasis being the first clinical manifestation of the tumor and review all the cases published to date, providing a new original clinical case with very specific histopathological characteristics. We systematically reviewed the literature in order to find all the cases of primary lung tumors that appeared with a gingival metastasis as the first manifestation. The search process involved a total of 1916 articles. After reading the latter, 15 (one of them with two different cases) met the inclusion criteria. Of the 15 articles, 6 were rated as medium quality (40%) and 9 as high quality (60%). We present a lung adenocarcinoma that first manifested as a metastasis in the gum, simulating a benign lesion. The unusually high growth rate of this lesion should conduct to have other diagnostic possibilities, and histopathological confirmation is essential.
RESUMO
OBJECTIVE: To evaluate the success and survival rates of dental implants in patients with oral lichen planus (OLP). METHOD AND MATERIALS: A narrative review literature search was conducted in the PubMed/Medline, Scopus, and Cochrane databases for articles published between 1990 and April 2013, using key search words "dental implants" and "oral lichen planus". RESULTS: This review did not identify any publications that were randomized controlled trials. A total of 60 OLP patients and 199 dental implants were analyzed. Three cases of OLP-related oral squamous cell carcinoma were reported. CONCLUSION: The extent and severity of underlying disease should be determined before dental implant placement.
