The rate is higher in males at 1.4 and lower in females at 0.6. [83] Table 1 provides age-standardised incidence and mortality rates for oral cancer based on the location in the mouth. The location 'other mouth' refers to the buccal mucosa, the vestibule and other unspecified parts of the mouth. The data suggests lip cancer has the highest ...
[1] [13] The underlying causes for this disease are extreme poverty, malnutrition, other causes of immunosuppression, underlying infections, and poor oral health. [1] The disease principally affects extremely impoverished and malnourished children between 2 and 6 years old in tropical regions.
AC almost always affects the lower lip and only rarely the upper lip, probably because the lower lip is more exposed to the sun. [7] In the unusual cases reported where it affects the upper lip, this may be due to upper lip prominence. [7] The commissures (corners of the mouth) are not usually involved. [2] [6]
More simply, epulis fissuratum is where excess folds of firm tissue form inside the mouth, as a result of rubbing on the edge of dentures that do not fit well. It is a harmless condition and does not represent oral cancer. Treatment is by simple surgical removal of the lesion, and also by adjustment of the denture or provision of a new denture.
In 1996, the number of cases were estimated around 2.5 million worldwide but there is no population-base data as it is not notifiable disease. In India, the prevalence is estimated 0.2–2.3% in males and 1.2–4.6% in females; with age range of 11 to 60 years. It is widely reported in South Asian diaspora in Europe, North America and South Africa.
Diagramatic representation of mucosal erosion (left), excoriation (center), and ulceration (right) Simplistic representation of the life cycle of mouth ulcers. An ulcer (/ ˈ ʌ l s ər /; from Latin ulcus, "ulcer, sore") [2] is a break in the skin or mucous membrane with loss of surface tissue and the disintegration and necrosis of epithelial tissue. [3]
Usually this lesion is reversible if the tobacco habit is stopped completely, [6] even after many years of use. [1] In one report, 98% of lesions disappeared within 2 weeks of stopping tobacco use. [3] The risk of the lesion developing into oral cancer (generally squamous cell carcinoma [6] and its variant verrucous carcinoma) [1] is relatively ...
Histopathology of irritation fibroma. Low magnification (left) characteristically [1] shows a nonencapsulated nodular mass. High magnification (right) shows fibrous connective tissue with collagen bundles, and some blood vessels and fibroblasts. Specialty: Gastroenterology: Symptoms: Palpable nodule: Frequency: 1–2% of adults [2]
