    Sarcoidosis is a disease of unknown cause characterized by non-necrotizing ("non-caseating") granulomas in multiple organs and body sites, [12] most commonly the lungs and lymph nodes within the chest cavity. Other common sites of involvement include the liver, spleen, skin, and eyes.

    It also frequently causes an increase in 1,25-dihydroxy vitamin D, the active metabolite of vitamin D, which is usually hydroxylated within the kidney, but in sarcoidosis patients, hydroxylation of vitamin D can occur outside the kidneys, namely inside the immune cells found in the granulomas the condition produces. 1,25-dihydroxy vitamin D is ...

    Liver cysts are common. They are fluid-filled contained structures within the liver. Simple liver cysts are seen most commonly in women and kids. [2] In terms of pathophysiology, they are formed in response to developmental events and in response to trauma and inflammation. [2]

  6. Gumma (pathology) - Wikipedia

    en.wikipedia.org/wiki/Gumma_(pathology)

    Gummas have a firm, necrotic center surrounded by inflamed tissue, which forms an amorphous proteinaceous mass. The center may become partly hyalinized.These central regions begin to die through coagulative necrosis, though they also retain some of the structural characteristics of previously normal tissues, enabling a distinction from the granulomas of tuberculosis where caseous necrosis ...

    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. However, many biopsies can be nonspecific and 50% provide too little information for the diagnosis of GPA. [12]

  8. Macrophage - Wikipedia

    en.wikipedia.org/wiki/Macrophage

    Within the fat tissue of CCR2 deficient mice, there is an increased number of eosinophils, greater alternative macrophage activation, and a propensity towards type 2 cytokine expression. Furthermore, this effect was exaggerated when the mice became obese from a high fat diet. [ 121 ]

  9. Schistosomiasis - Wikipedia

    en.wikipedia.org/wiki/Schistosomiasis

    This condition occurs mainly in children and adolescents due to early immune reaction to eggs trapped within the periportal and presinusoidal spaces of the liver creating numerous granulomas. [19] Liver function is not affected, and the severity of liver and spleen enlargement is correlated to the intensity of the infection. [19] It is ...
