An open sore on an external or internal body surface usually accompanied by disintegration of tissue and pus.
A localized necrotic lesion of the skin or a mucous surface.
An interruption of continuity of a surface with an inflamed base. Any open sore other than a wound.
A lesion on the skin or on a mucous membrane.
A craterlike sore on the skin or mucous membrane.
A break in skin or mucous membrane accompanied by tissue disintegration.
An open sore in the skin or in a mucous membrane, which is inflamed and difficult to heal.
Ulcers are characterized by a persistent, burning pain in the abdomen as a result of a sore or lesion in the lining of the stomach or duodenum. Prevalence rates from the National Digestive Diseases Information Clearinghouse (NDDIC, 1998) indicate that about 4 million people are affected by ulcers, and that approximately 40,000 people have surgery for persistent problems, with complications resulting in death for 6,000 of them. Although ulcers can develop at any age, they are rare in teenagers, and even rarer in children.
Circumscribed lesion of the skin or mucous membrane of an organ formed by necrosis of tissue resulting from an infectious, malignant, or inflammatory process. Two types of ulcers are decubitus ulcers (bedsores) and peptic ulcers. Also known as ulceration.
Slow-healing sore on the surface of an organ or tissue resulting from tissue necrosis.
An opening in the skin or mucous membrane that has become sore and inflamed. May occur outside or inside the body.
A sore or wound on the skin or a mucous membrane. A peptic ulcer is one that affects the mucous membrane lining the lower esophagus, stomach, or duodenum.
A break in the skin or in the mucous membrane lining the alimentary tract that fails to heal and is often accompanied by inflammation. Ulcers in the skin include varicose ulcers complicating varicose veins, due to defective circulation; bedsores (decubitus ulcers), due to pressure; and rodent ulcers, due to malignant growth. For ulcers of the alimentary tract, duodenal ulcer, gastric ulcer, peptic ulcer.
Destruction of the skin’s surface tissues resulting in an open sore. A similar breach may occur in the surface of the mucous membrane lining body cavities for example, the stomach, duodenum or colon. Usually accompanied by pain and local inflammation, ulcers can be shallow or deep, with a crater-like shape. An ulcer may heal naturally, but on certain parts of the body legs or bony protuberances they can become chronic and difficult to treat. When an ulcer heals, granulations (well-vascularized connective tissue) form which become fibrous and draw the edges of the ulcer together. Any damage to the body surface may develop into an ulcer if the causative agent is allowed to persist for example, contact with a noxious substance or constant pressure on an area of tissue with poor circulation. Treatment of skin ulcers is effected by cleaning the area, regular dry dressings and local or systemic antibiotics depending upon the severity of the ulcer.
A lesion of the skin or mucous membranes marked by inflammation, necrosis, and sloughing of damaged tissues. A wide variety of insults may produce ulcers, including trauma, caustic chemicals, intense heat or cold, arterial or venous stasis, cancers, drugs (e.g., nonsteroidal anti-inflammatory drugs), and infectious agents such as Herpes simplex or Helicobacter pylori.
Disease involving the chronic destruction of the lining of the stomach or duodenum.
Open lesion on the skin or mucous membrane of the body, accompanied by pus and loss of skin depth and possibly weeping fluids or pus.
A crater-like sore on the skin or mucous membrane caused by infectious, inflammatory or malignant conditions. An ulcer developing in the stomach, lower esophagus or upper small intestine is a type of peptic ulcer.
An open sore, especially one in the lining of the stomach or other part of the digestive tract.
A disruption in the integrity of the skin or mucous membrane is referred to as a lesion. This affliction has the potential to develop into an inflammatory condition, resembling a sore that may discharge pus.
An ulcer is a lesion that forms on the skin or a mucous membrane due to the erosion of surface tissues. Ulcers can take the form of shallow or deep, crater-like depressions, often accompanied by inflammation and pain. An indolent ulcer refers to a type that heals gradually and lacks pain sensation.
Skin ulcers frequently emerge on the leg, primarily due to insufficient blood circulation or poor drainage from the limb. Occasionally, certain types of skin cancers like basal cell carcinomas or squamous cell carcinomas can lead to ulceration. In rare instances, a cancerous growth might develop in the skin surrounding a persistent ulcer.
Mucous membrane ulcers predominantly arise within the digestive tract, which encompasses a series of tubular structures extending from the mouth to the anus. These ulcers encompass mouth ulcers, peptic ulcers (affecting the stomach or duodenum), and the ulcers associated with ulcerative colitis, an inflammatory condition affecting the colon or rectum.
Ulcers can also impact the skin or mucous membranes in the genital area. The majority of genital ulcers stem from sexually transmitted infections. Illustrative of this category are hard chancres, which manifest in the initial phase of syphilis, as well as soft chancres.
Ulcers can also form on the cornea, the clear layer covering the front of the eyeball.
A disruption in the lining of the lower segment of the large intestine that doesn’t properly mend characterizes this condition. Indications might encompass anal bleeding, discharge of mucus from the anus, a sensation of incomplete rectal emptying (known as tenesmus), and discomfort. Concurrently, instances of diarrhea or constipation might arise. Additionally, rectal prolapse, wherein a portion of the rectum protrudes outside the anus, is frequently associated with this condition.
Diagnosis can be established through rectal endoscopy (utilizing a visual instrument) and the retrieval of a tissue sample for biopsy. Treatment options might involve the use of laxatives and adoption of a high-fiber diet. In some cases, surgical intervention could be advised to remove the ulcer.
The deterioration of skin or mucous membrane surface, frequently leading to the breakdown of underlying tissues.
