OBJECTIVE To evaluate the clinical potential of fluorescence spectroscopy (a noninvasive technique for assessing the chemical and morphologic composition of tissue) for in vivo detection of oral cavity neoplasia. DESIGN A fluorescence spectroscopy system recorded spectra from oral cavity sites in 8 healthy volunteers and in 15 patients with premalignant or malignant oral cavity lesions at 337...

INTRODUCTION Recent trends in incidence rates for tobacco-related cancers may vary geographically because of variation in socioeconomic status and in history of comprehensive state tobacco control programs (starting with California in 1989). Recent trends in risk factors are likely to affect cancer incidence rates at the youngest ages METHODS Trends in age-adjusted incidence rates for cancers...

objective: oral non- hodgkin’s lymphoma (nhl) is a relatively rare neoplasm that may develop in the soft tissues or jaw bones, with or without node or marrow involvement. oral lymphomas are often difficult to diagnose as there are no characteristic clinical features and usually appear as non-tender swellings.   case: we describe clinical, radiographic, histopathological and immunohistochemical ...

OBJECTIVE To determine whether periodontitis is associated with human papillomavirus (HPV) status of head and neck squamous cell carcinoma (HNSCC). DESIGN AND SETTING Hospital-based case-control study in a comprehensive cancer center. PATIENTS Evaluation included all patients diagnosed with incident primary squamous cell carcinoma of the oral cavity, oropharynx, and larynx between 1999 and ...

Cancer incidence in humans has gradually increased over the last century. Surgical, radio, chemotherapeutic and biological treatments have experienced important advances, with concomitant reduction in the morbidity associated with the radical surgical practices of the past. The term “oral cancer” includes a diverse group of tumors arising from the oral cavity (Khalili, 2008). Usually included a...

OBJECTIVE To present a rare case of breast carcinoma initially presenting as an oral cavity mass. STUDY DESIGN Case report with review of the literature. RESULTS A case is presented of a postmenopausal woman with a remote history of treated breast carcinoma who was declared disease-free 2 years before presentation. She presented with an enlarging vestibule mass consistent with metastatic br...

Numerous microorganisms, such as bacteria, viruses and fungi, inhabit the oral cavity, and it has been pointed out that poor oral hygiene and chronic periodontitis increase the risk of oral squamous cell carcinoma (OSCC). However, the molecular mechanism whereby the risk of OSCC is increased under such conditions has not yet been clarified. Microbes in the oral cavity may elicit both innate and...

Although the human papillomavirus (HPV) vaccine was introduced primarily as a cervical cancer prevention vaccine, HPV has a causal role in several types of cancer. This article reviews the epidemiological evidence for the role of HPV in human cancer, and describes Australian trends in these cancers. HPV is a necessary cause of cervical cancer. The currently vaccine-preventable subtypes of HPV 1...

background and aim: oral mucosal lesions have various prevalence rates among different populations. few studies have evaluated the frequency of oral mucosal lesions in iranian population. this study aimed to determine the frequency of oral mucosal lesions and the related factors.                        materials and methods: this descriptive study was conducted based on the data in the archives...

Spindle cell neoplasms are defined as neoplasms that consist of spindle-shaped cells in the histopathology. Spindle cell neoplasms can affect the oral cavity. In the oral cavity, the origin of the spindle cell neoplasms may be traced to epithelial, mesenchymal and odontogenic components. This article aims to review the spindle cell neoplasms of the oral cavity with emphasis on histopathology. ...
