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]
As with the licking of wounds by people, wound licking by animals carries a risk of infection. Allowing pet cats to lick open wounds can cause cellulitis [53] [54] and sepsis [55] [56] due to bacterial infections. Licking of open wounds by dogs could transmit rabies if the dog is infected with rabies, [57] although this is said by the CDC to be ...
Blood from the face or mouth, if swallowed, can cause vomiting, which can itself present a threat to the airway because it has the potential to be aspirated. [26] Since airway problems can occur late after the initial injury, it is necessary for healthcare providers to monitor the airway regularly.
The diagnosis is usually made on the clinical appearance alone, and biopsy is not usually indicated. The histologic appearance is one of marked hyperparakeratosis producing a ragged surface with many projections of keratin. Typically there is superficial colonization by bacteria.
Timing is important to wound healing. Critically, the timing of wound re-epithelialization can decide the outcome of the healing. [11] If the epithelization of tissue over a denuded area is slow, a scar will form over many weeks, or months; [12] [13] If the epithelization of a wounded area is fast, the healing will result in regeneration.
The median time interval between the onset of symptoms and the diagnosis was 6 years, with a range of 26 days to 14 years. This suggests that the symptoms of MAGIC syndrome may manifest relatively long after the initial onset of symptoms. During the course of MAGIC syndrome, the signs and symptoms of BD may typically occur before those of RP. [4]
Angina bullosa haemorrhagica is a condition of the mucous membranes characterized by the sudden appearance of one or more blood blisters within the oral cavity. [1]: 808 The lesions, which may be caused by mild trauma to the mouth tissues such as hot foods, typically rupture quickly and heal without scarring or further discomfort. [2]
Reconstruction can include skin grafts or flaps. [7] Skin grafting and flap procedures use the patient’s own healthy soft tissues to heal a wound. Debridement describes the process of surgically removing unhealthy tissue from an area. After an injury, portions of the soft tissue may be able to survive while other parts may be dead.
