  2. Granuloma - Wikipedia

    en.wikipedia.org/wiki/Granuloma

    Examples of this use of the term granuloma are the lesions known as vocal cord granuloma (known as contact granuloma), pyogenic granuloma, and intubation granuloma, all of which are examples of granulation tissue, not granulomas. "Pulmonary hyalinizing granuloma" is a lesion characterized by keloid-like fibrosis in the lung and is not ...

  3. Granulomatosis with polyangiitis - Wikipedia

    en.wikipedia.org/wiki/Granulomatosis_with...

    These granulomas are the main reason for the name granulomatosis with polyangiitis, although it is not an essential feature. Nevertheless, necrotizing granulomas are a hallmark of this disease. Many biopsies can be nonspecific, though, and 50% provide too little information for the diagnosis of GPA. [12]

  4. Chronic granulomatous disease - Wikipedia

    en.wikipedia.org/wiki/Chronic_granulomatous_disease

    Chronic granulomatous disease (CGD), also known as Bridges–Good syndrome, chronic granulomatous disorder, and Quie syndrome, [1] is a diverse group of hereditary diseases in which certain cells of the immune system have difficulty forming the reactive oxygen compounds (most importantly the superoxide radical due to defective phagocyte NADPH oxidase) used to kill certain ingested pathogens. [2]

  5. Epithelioid cell - Wikipedia

    en.wikipedia.org/wiki/Epithelioid_cell

    Granulomas try to wall off these organisms and prevent their further growth and spread. Historically widespread and destructive diseases such as tuberculosis, leprosy and syphilis are granulomatous conditions. Granuloma formation is also the feature of many more contemporary conditions, like fungal infections, sarcoidosis and Crohn's disease. [4]

  6. Granulation tissue - Wikipedia

    en.wikipedia.org/wiki/Granulation_tissue

    Examples of granulation tissue can be seen in pyogenic granulomas and pulp polyps. Its histological appearance is characterized by proliferation of fibroblasts and thin-walled, delicate capillaries ( angiogenesis ), and infiltrated inflammatory cells in a loose extracellular matrix.

  7. Pyogenic granuloma - Wikipedia

    en.wikipedia.org/wiki/Pyogenic_granuloma

    This is especially true if the granuloma is located on the scalp. [medical citation needed] Epulis granulomatosum is a variant of pyogenic granuloma that forms only on gingiva, and is often seen forming in a recent extraction socket. Pyogenic granulomas appear on the gingiva in 75% of cases, more often in the maxillary than mandibular jaw ...

  8. Giant cell - Wikipedia

    en.wikipedia.org/wiki/Giant_cell

    A giant cell (also known as a multinucleated giant cell, or multinucleate giant cell) is a mass formed by the union of several distinct cells (usually histiocytes), often forming a granuloma. [1] Although there is typically a focus on the pathological aspects of multinucleate giant cells (MGCs), they also play many important physiological roles.

  9. Granulomatous–lymphocytic interstitial lung disease - Wikipedia

    en.wikipedia.org/wiki/Granulomatous–lymphocytic...

    Granulomatous–lymphocytic interstitial lung disease (GLILD) is a lung complication of common variable immunodeficiency disorders (CVID). It is seen in approximately 15% of patients with CVID. [ 1 ] It has been defined histologically as the presence of (non-caseating) granuloma and lymphoproliferation in the lung. [ 1 ]
