Lesion indicative of a chronic inflammatory response, characterized by the accumulation of white blood cells around an offending agent for the purpose of walling off the agent from the rest of the body.
consolidated inflammatory response composed of cellular nodules (mixed lymphocytes, macrophages, plasma cells, epithelioid cells).
a chronic inflammatory lesion.
An indefinite term applied to nodular inflammatory lesions, usually small, granular, -- in plain English, a tiny bump or mass that is distinct from surrounding tissue and that may be inflamed (red, swollen and painful) or may be grainy, or both. Neuropathy: A disorder affecting the nervous system
mass of red, irritated tissue in gi track
An excessive amount of non-healing tissue in a wound.
a tumor composed of granulation tissue resulting from injury or inflammation or infection
a circumscribed structure formed around the site of irritation
a compact accumulation of cells, comprised mainly of monocytes or their variants, macrophages, epithelioid cells, and giant cells
a focal area of chronic inflammation produced by circulating monocy
a healthy collection of living cells
a highly vascularized tissue containing a profuse infiltrate of immunological competent cells i
a lesion formed in response to infection by some intracellular pathogens
a localized nodular inflammation which has a typical pattern when the involved tissue examined under a microscope
a lump caused by an overgrowth of inflamed tissue
a mass that is formed around an irritation to the body's defense mechanisms
an abnormal structure built from at least two activated macrophages adhering to one another
a scar from old infection
a site of chronic inflammation usually triggered by persistent infectious agents such as mycobacteria or by a nondegradable foreign body
a small area of inflammation in the body, usually in the lungs, due to injury, such as from an infection
a small area of inflammatory tissue in the body due to tissue injury, such as from infection
a solid grouping of inflammatory cells coming together in a lump or solid structure
A small lump resulting from chronic inflammation
a collection of white blood cells in a site of infection, which can continue to collect after the infection has cleared.
A granuloma is similar to a scar in that it represents the body's attempt to wall off and heal an infection.
A benign growth that typically occurs in the posterior (back) part of the larynx, either directly on the vocal fold, or on one of the mucosal surfaces nearby. The growth may prevent glottic closure, causing vibration to be weak or non-existent. This could cause a weak or breathy voice, or frequent "breaks" in the voice. The lesion may also interfere with vibration, causing a rough, irregular sound. The voice may fatigue easily and become worse sounding with continued use. A lesion that is not directly on the vocal fold may not interfere with voice quality, but can be very irritating and even painful. A large enough lesion may obstruct the airway. Term found in Types of Voice Disorders: Granuloma.
Nodular lesions caused by an organized inflammatory response to the TB bacilli, often becoming calcified.
discrete collection of chronic inflammatory cells that form a mass in the tissue
Localized collection of macrophages (histiocytes).
A complex mass of tissue which has a variety of causes. Granulomatous disease is generally thought to be nonspecific in nature. It has a wide differential diagnosis. It is commonly seen in biopsies of patients with Crohn's disease. Granulomas are also seen in the liver. In this condition it is called granulomatous hepatitis.
A mass of tissue that forms at a site of inflammation, injury, or infection as a part of the healing process.
mass of red, irritated tissue in the GI tract found in Crohn's disease.
a mass of granulation tissue developing at the tip of a tooth root, usually the result of an infection within the tooth's pulp (which contains blood vessels, nerves and connective tissue).
an inflammatory lesion containing phagocytes.
A tumor-like mass or nodule of tissue.
a mass of nodular granulation tissue caused by inflammation, injury or infection.
A tumor-like mass of inflammatory tissue consisting of a central collection of macrophages, often with multinucleated giant cells, surrounded by lymphocytes.
A granuloma is one of a number of forms of localized nodular inflammation found in tissues. The fact that a granuloma is localized is important. So is its nodularity. Granulomas have a typical pattern when examined under a microscope. See the entire definition of Granuloma
a site of chronic inflammation where the immune system has problems removing the antigen (either Mycobacteria in TB or a self antigen in autoimmune disease). It is characterised by a central area of macrophages surrounded by T cells. Haemolytic Anaemia - anaemia resulting from increased destruction of red blood cells (which contain the haemoglobin) caused by autoantibodies that target them for destruction.
A special type of INFLAMMATION characterized by accumulations of macrophages, some of which coalesce into "giant cells." Granulomatous inflammation is especially characteristic of tuberculosis, some deep fungal infections (like histoplasmosis and coccidioidomycosis), sarcoidosis (a disease of unknown cause), and reaction to foreign bodies.
A round or oval collection of inflammatory cells including lymphocytes, macrophages and neutrophils.
Mass of inflamed granulation tissue that usually converted into abcess.
A mass of inflamed granulation tissue, usually associated with ulcerated infections.
A special type of inflammation characterized by accumulations of macrophages, some of which coalesce into "giant cells." Granulomatous inflammation is especially characteristic of tuberculosis, some deep fungal infections, sarcoidosis, reaction to foreign bodies and several skin diseases of unknown cause.
A small mass of healing tissue caused by chronic infection.
overgrowth of highly vascular (good blood supply) soft tissue, typically caused from chronic irritation of a nail, such as an ingrown nail. A good example is the red tissue on the side of the nail as shown in the picture of the ingrown nail below.
overgrowth of highly vascular (good blood supply) soft tissue, typically caused from chronic irritation of a nail, such as an ingrown nail. (You can see an example of a granuloma in the reddish tissue on the sides of the nail pictured under the heading of ingrown nails.)
A granuloma is a histological (pathological) term refering to chronic inflammation in which there are several types of inflammatory cells including giant cells. Granulomas form in response to foreign bodies, certain infections (tuberculosis, leprosy) and inflammatory skin diseases (granuloma annulare [illustrated], granuloma faciale, sarcoidosis).
a focal collection of activated macrophages.
A ball of inflamed tissue, commonly formed after vasectomy due to sperm leaking into the vas deferens.
In medicine (anatomical pathology), a granuloma is a group of epithelioid macrophages surrounded by a lymphocyte cuff. Granulomas are small nodules that are seen in a variety of diseases such as Crohn's disease, tuberculosis, sarcoidosis, berylliosis and syphilis. It is also a feature of Wegener's granulomatosis and Churg-Strauss syndrome, two related autoimmune disorders.
