Granulation tissue is composed of tissue matrix supporting a variety of cell types, [3] most of which can be associated with one of the following functions: formation of extracellular matrix; operation of the immune system; vascularisation; An excess of granulation tissue (caro luxurians) is informally referred to as hypergranulation or "proud ...
A pyogenic granuloma or lobular capillary hemangioma [3] is a vascular tumor that occurs on both mucosa and skin, and appears as an overgrowth of tissue due to irritation, physical trauma, or hormonal factors. [4] [5] It is often found to involve the gums, skin, or nasal septum, and has also been found far from the head, such as in the thigh. [6]
Intubation granuloma is a benign growth of granulation tissue in the larynx or trachea, which arises from tissue trauma due to endotracheal intubation. [1] This medical condition is described as a common late complication of tracheal intubation, specifically caused by irritation to the mucosal tissue of the airway during insertion or removal of the patient's intubation tube.
In pathology, a granuloma is an organized collection of macrophages. [1] [6] In medical practice, doctors occasionally use the term granuloma in its more literal meaning: "a small nodule". Since a small nodule can represent any tissue from a harmless nevus to a malignant tumor, this use of the term is not very
Periapical granuloma, [1] also sometimes referred to as a radicular granuloma or apical granuloma, is an inflammation at the tip of a dead (nonvital) tooth. It is a lesion or mass that typically starts out as an epithelial lined cyst, and undergoes an inward curvature that results in inflammation of granulation tissue at the root tips of a dead tooth.
The tissue is often friable, measuring <2 cm in most cases. All tissue should be processed in order to exclude a concurrent cholesteatoma. [3] By microscopic exam, the polypoid appearance is maintained, showing a granulation-type tissue reaction with edematous stroma and a rich investment by capillaries.
Periapical is defined as "the tissues surrounding the apex of the root of a tooth" and a cyst is "a pathological cavity lined by epithelium, having fluid or gaseous content that is not created by the accumulation of pus." [2]
A mast cell (also known as a mastocyte or a labrocyte [1]) is a resident cell of connective tissue that contains many granules rich in histamine and heparin.Specifically, it is a type of granulocyte derived from the myeloid stem cell that is a part of the immune and neuroimmune systems.
