BACKGROUND Rhabdomyosarcoma is a malignant neoplasm of primitive mesenchyme exhibiting skeletal muscle differentiation. Oral rhabdomyosarcoma is rare and accounts for only 0.04% of all head and neck malignancies. METHODS A 33-year-old woman presented with an erythematous gingival mass involving the anterior maxillary gingiva. The lesion had been present(More)
The 5-year survival rate for oral cavity cancer is poorer than for breast, colon or prostate cancer, and has improved only slightly in the last three decades. Hence, new therapeutic strategies are urgently needed. Here we demonstrate by tissue micro array analysis for the first time that RNA-binding protein La is significantly overexpressed in oral squamous(More)
BACKGROUND Alveolar ridge keratosis (ARK) is not widely recognized as a distinct clinicopathologic entity, and it often is included in studies of oral leukoplakia (OL), thereby implying premalignant potential. The authors' objectives were to characterize the clinicopathologic features of ARK and determine whether removing ARK from the OL category would(More)
BACKGROUND Several recent reports suggest an increasing incidence of oral squamous cell carcinoma (OSCC) among young persons in many regions of the world--a trend which is particularly concerning given the overall stabilization or even decline in incidence rates for head and neck cancer in general. The aim of this study is to determine whether there has(More)
Oral cavity squamous cell carcinoma (OC-SCC) is the most common malignancy of the head and neck (excluding nonmelanoma skin cancer). Recent trends have shown a dramatic rise in the incidence of oropharyngeal squamous cell carcinoma (OP-SCC), with a marked increase in lesions related to human papillomavirus infection. This update presents the latest evidence(More)
Head and neck squamous cell carcinoma (HNSCC) is an aggressive malignancy, and despite advances in treatments, the 5-year survival has remained at less than 50%. One treatment strategy is to focus on patients with premalignant oral lesions that carry a high-risk for developing recurrent premalignant lesions and HNSCC disease. As an initial attempt to(More)
Common superficial oral lesions include candidiasis, recurrent herpes labialis, recurrent aphthous stomatitis, erythema migrans, hairy tongue, and lichen planus. Recognition and diagnosis require taking a thorough history and performing a complete oral examination. Knowledge of clinical characteristics such as size, location, surface morphology, color,(More)
UNLABELLED Polyaromatic hydrocarbons, including benzo[a]pyrene (BP), are major tobacco carcinogens. Their carcinogenic effects require metabolic activation by cytochrome p450 (CYP) enzymes. Relative CYP isoform expression is related to tissue-specific tobacco-related squamous cell carcinoma (SCC) susceptibility. There have been conflicting reports regarding(More)
Careful examination of the oral cavity may reveal findings indicative of an underlying systemic condition, and allow for early diagnosis and treatment. Examination should include evaluation for mucosal changes, periodontal inflammation and bleeding, and general condition of the teeth. Oral findings of anemia may include mucosal pallor, atrophic glossitis,(More)
Schwannomas are benign neoplasms originating from the neural sheath and occurring most often in the soft tissues of the head and neck. Intraosseous schwannomas, however, are rare. The most common site of occurrence for these unusual lesions is the mandible. This article documents a case of an intramandibular schwannoma and provides a review of the(More)
