Secondary oral cavity neoplasms are rare. We describe a case of an indurated, nonulcerating gingival lesion in a 59-year-old nonsmoking man with no family history of lung cancer. The lesion was the presenting symptom of metastatic lung adenocarcinoma. Reviewing the literature, we find that primary lung cancer among men is one of the most common cancers to metastasize to the oral cavity. Renal a...

During the past 25 years, there has been disagreement regarding the existence of H. pylori in the oral infection. It was proposed that no living H. pylori exists in the oral cavity and that the positive results detected by a polymerase chain reaction (PCR) in the oral cavity may be a fragment of H. pylori, instead of living bacteria, as part of a reflux from the stomach: H. pylori could not be ...

Introduction: Colon adenocarcinoma is one of the foremost causes of cancer mortality. Oral metastasis of colon adenocarcinoma is, however, rare and indicates an end-stage disease process.   Case Report: We report a case of a 69-year-old female with a gingival mass diagnosed with colon adenocarcinoma and liver metastasis after one year. A swelli...

AIM The aim of this study is to estimate oral cavity cancer mortality for Iranian population, using Bayesian approach in order to revise this misclassification. BACKGROUND Mortality is a familiar projection to address the burden of cancers, but according to Iranian death registry, about 20% death statistics were still recorded in misclassified categories. PATIENTS AND METHODS We analyzed na...

Linear epidermal nevus is an uncommon diagnosis of benign lesions of the oral cavity. It is characterized by a congenital malformation arising from the ectoderm cells, which are arranged according to a typical linear configuration known as Blaschko's lines. We report a case of linear epidermal nevus of oral cavity in a 51-year-old lady or woman. The linear epidermal nevus of the oral cavity, al...

BACKGROUND The pupose of this study was to describe variations in incidence and resection rates of patients with oral cavity squamous cell carcinoma (SCC) in Ontario. METHODS All oral cavity SCCs in Ontario between 2003 and 2010 were identified from the Ontario Cancer Registry. Incidence and resection rates along with variations in care were compared by sociodemographic factors and Ontario he...

Infection with the Epstein-Barr virus (EBV) is often subclinical in the presence of a healthy immune response; thus, asymptomatic infection is largely uncharacterized. This study analyzed the nature of EBV infection in 20 asymptomatic immunocompetent hosts over time through the identification of EBV strain variants in the peripheral blood and oral cavity. A heteroduplex tracking assay specific ...
