Oral cavity T-cell lymphoma occurs rarely. This case report describes a patient with such a tumor. The case was a 75 years old man presented with a painless swelling on his hard palate mucosa. He had suffered from nose- bleeding and nasal obstruction. Pathology revealed the presence of a T-cell lymphoma tumor in the palate. Though rare, the signs and symptoms of the case suggest that T-cell lym...

Introduction: A reliable source of cultured keratinocytes is essential as a component of oral mucosa substitutes to treat burns and wounds of the oral and maxillofacial region. Primary monolayer cell cultures have been also extremely helpful in the study of the basic biology and responses to stimuli, of both oral and skin keratinocytes, and many studies have used them. There are two techniques ...

Oral carcinogenesis is a multi-step process. One possible step is the development of potentially malignant disorders known as leukoplakia and erytroplakia. The objective of this study was to use immunohistochemistry to analyze the patterns of expression of the cell-cycle regulatory proteins p53 and p16(INK4a) in potentially malignant disorders (PMD) of the oral mucosa (with varying degrees of d...

Lichen planus is a mucocutaneous disease of inflammatory nature and unknown etiology. It is characterized by a cell-mediated immunological response to induced antigenic change in skin and/or mucosa. The possible malignant transformation of lichen planus remains a subject of controversial discussions in the literature. hMSH2 is one of the human DNA mismatch repair (hMMR) genes and it plays an im...

The research has the following aims: 1: to verify the applicability of capillaroscopic investigation to oral mucosa; 2: to propose oral mucosa as an alternative to the fingernail fold for capillaroscopic investigation; 3: to describe the characteristics of the microcirculation of oral mucosa in healthy subjects. 100 healthy patients were examined. The characteristics of the micro-circulation in...

BACKGROUND Dyspigmentation of the oral mucosa has a multitude of aetiological causes. Retigabine, a new antiepileptic drug, has the potential side effect of inducing a blue/purple pigmentation of the oral mucosa in addition to the skin, lips, nails and retina of the eyes. This article presents a unique case of dyspigmentation present in the oral mucosa of the hard palate which has previously be...

High-risk human papillomaviruses (HR-HPV) are considered necessary for the development of cervical cancer. Furthermore, there is no doubt that some types of oral squamous cell carcinoma are associated with HR-HPV. The epidemiology of oral HPV infections in healthy subjects remains unclear due to a lack of knowledge. The objective of this study was to investigate the epidemiology of human papill...

The oral cavity can be affected by a wide variety of disorders characterized by inflammation of the gingiva and/or oral mucosa. In dogs and cats, differential diagnoses for generalized oral inflammatory disorders include plaque-reactive mucositis, chronic gingivostomatitis, eosinophilic granuloma complex, pemphigus and pemphigoid disorders, erythema multiforme, and systemic lupus erythematosus....

Burns of the oral mucosa can be caused by heat, cold, radiation, electricity and mechanical or chemical stimuli. Acids, alkalis and salts can cause considerable damage to the oral mucosa, membranes and lips. Most damage is found in the oropharynx, besides the pharynx and tonsils, the alveolar mucosa of the tongue and the masticatory mucosa of the palate or gingiva show localized or diffused dam...
