aphthous ulcer (redirected from Cankersore)

ulcer [ul´ser]

a local defect, or excavation of the surface of an organ or tissue, produced by sloughing of necrotic inflammatory tissue.

aphthous ulcer a small painful ulcer in the mouth, approximately 2 to 5 mm in diameter. It usually remains for five to seven days and heals within two weeks with no scarring.

chronic leg ulcer ulceration of the lower leg caused by peripheral vascular disease involving either arteries and arterioles or veins and venules of the affected limb. Arterial and venous ulcers are quite different and require different modes of treatment. Venous stasis ulcers occur as a result of venous insufficiency in the lower limb. The insufficiency is due to deep vein thrombosis and failure of the one-way valves that act during muscle contraction to prevent the backflow of blood. Chronic varicosities of the veins can also cause venous stasis.

Patient Care. Stasis ulcers are difficult to treat because impaired blood flow interferes with the normal healing process and prolongs repair. Patient care is concerned with preventing a superimposed infection in the ulcer, increasing blood flow in the deeper veins, and decreasing pressure within the superficial veins.

decubitus ulcer pressure ulcer.

duodenal ulcer an ulcer of the duodenum, one of the two most common types of peptic ulcer.

gastric ulcer an ulcer of the inner wall of the stomach, one of the two most common kinds of peptic ulcer.

Hunner's ulcer one involving all layers of the bladder wall, seen in interstitial cystitis.

hypertensive ischemic ulcer a manifestation of infarction of the skin due to arteriolar occlusion as part of a longstanding vascular disease, seen especially in women in late middle age, and presenting as a red painful plaque on the lower limb or ankle that later breaks down into a superficial ulcer surrounded by a zone of purpuric erythema.

marginal ulcer a peptic ulcer occurring at the margin of a surgical anastomosis of the stomach and small intestine or duodenum. Marginal ulcers are a frequent complication of surgical treatment for peptic ulcer; they are difficult to control medically and often require further surgery.

peptic ulcer see peptic ulcer.

perforating ulcer one that involves the entire thickness of an organ, creating an opening on both surfaces.

phagedenic ulcer

1. any of a group of conditions due to secondary bacterial invasion of a preexisting cutaneous lesion or the intact skin of an individual with impaired resistance as a result of a systemic disease, which is characterized by necrotic ulceration associated with prominent tissue destruction.

2. tropical phagedenic ulcer.

pressure ulcer see pressure ulcer.

rodent ulcer ulcerating basal cell carcinoma of the skin.

stasis ulcer ulceration on the ankle due to venous insufficiency and venous stasis.

stress ulcer a type of peptic ulcer, usually gastric, resulting from stress; possible predisposing factors include changes in the microcirculation of the gastric mucosa, increased permeability of the gastric mucosa barrier to H⁺, and impaired cell proliferation.

trophic ulcer one due to imperfect nutrition of the part.

tropical ulcer

1. a lesion of cutaneous leishmaniasis.

2. tropical phagedenic ulcer.

tropical phagedenic ulcer a chronic, painful phagedenic ulcer usually seen on the lower limbs of malnourished children in the tropics; the etiology is unknown, but spirochetes, fusiform bacilli, and other bacteria are often present in the developing lesion, and protein and vitamin deficiency with lowered resistance to infection may play a role in the etiology.

varicose ulcer an ulcer due to varicose veins.

venereal ulcer a nonspecific term referring to the formation of ulcers resembling chancre or chancroid about the external genitalia; there are both sexually transmitted and other types.

canker sore. The cause is unknown, and treatment is limited to alleviating the symptoms.

ulcer, aphthous, recurrent (RAU)

n periodic episodes of aphthous lesions on nonkeratinized oral tissues lasting from 1 week to several months. Trauma and immunologic factors are involved in the etiology. The single or multiple discrete or confluent ulcers have a well-defined marginal erythema and a central area of necrosis with sloughing. Also called
canker sore and
recurrent aphthae.

ulcer, autochthonous

n See chancre.

ulcer, decubitus

n 1. a bedsore.
2. older term for a traumatic ulcer of the oral mucosa. More commonly called
traumatic ulcer.

Decubitus ulcer.

ulcer, diabetic

n an ulcer, usually of the lower extremities, associated with diabetes mellitus.

ulcer, herpetic

n an ulcer on keratinized orofacial tissues that is secondary to the vesicle of herpes simplex after the intact surface is broken by trauma to the lesion; a shallow ulcer with an irregular, erythematous border and a yellow-gray base. Contagious through all stages of lesion. Can be treated by topical acyclovir. Also called a
cold sore.

ulcer, Mikulicz's

n.pr See periadenitis mucosa necrotica recurrens.

ulcer, pemphigoid aphthous,

n a lesion located on the gingiva or mucous membranes due to a chronic disease of the autoimmune system. It is indicated by a wound with a thick wall that ruptures within 24 to 48 hours and leaves an eroded and painful surface area. It heals through the formation of a scar.

ulcer, peptic

n an ulcer of the stomach or duodenum. Most ulcers are associated with
H. pylori, a spiral-shaped bacterium that lives in the acidic environment of the stomach. They can also be caused or worsened by drugs such as aspirin and other NSAIDs.

ulcer, pterygoid

n See aphtha, Bednar's.

ulcer, rodent,

n See carcinoma, basal cell.

ulcer, traumatic,

n an ulcer that is caused by trauma. It can be due to faulty oral hygiene, rough foods, oral habits, poor-fitting dentures, or inadvertent mastication or biting of oral tissues. The offending cause may need to be removed by the patient or clinician. After this treatment, it must heal within a 2-week period to rule out any oral cancer concerns. The older term in dentistry is
decubitus ulcer.

A. A canker sore (aphthous stomatitis) is an illness that causes small ulcers to appear in the mouth, usually inside the lips, on the cheeks, or on the tongue. What causes aphthous stomatitis (canker sores)?
The exact cause of this disease is not known. There are many factors that are thought to be involved with the development of canker sores, including:

Weakened immune system
Certain allergies may cause the lesions to appear, such as:
Coffee
Chocolate
Cheese
Nuts

Potatoes
Stress
Viruses and bacteria

The following are the most common symptoms of aphthous stomatitis. However, each child may experience symptoms differently. Symptoms may include:

Q. Is it possible to prevent appearance of oral aphthae? I get these a lot and lately I've heard it comes as a result of stress or weak immune system. Is that true? Is there a way to make it go away forever????? anyone who has ever had this annoying thing in his mouth knows what I'm talking about... I know all the possible curing ways- I'm looking for prevention now...thanx!

A. welcome to my life! every time the air get's a little dry i get 1-3 aphthae and can't eat for the next 4-6 days. so i investigated a little, and i'm sorry but right now no one really knows what causes them. they know that from some reason the body get's an immune reaction in the oral mucosa and that causes an ulcer. but a friend of mine went to an Ayurveda therapist that told him to stop eating tomatoes and eggplants (in any way, cooked,baked,fried) and he says he stop getting aphthae. so you might try Ayurveda for prevention. it could help...
