The cause of sarcoidosis is unknown. [2] Some believe it may be due to an immune reaction to a trigger such as an infection or chemicals in those who are genetically predisposed. [12] [13] Those with affected family members are at greater risk. [4] Diagnosis is partly based on signs and symptoms, which may be supported by biopsy. [6]
Sarcoidosis is a disease of unknown cause that leads to the development of granulomas in various organs. While the lungs are typically involved, other organs may equally be affected. Some subforms of sarcoidosis, such as Löfgren syndrome, may have a particular precipitant and have a specific course. It is unknown which characteristics ...
Scar sarcoid (also known as "Sarcoidosis in scars") is a cutaneous condition characterized by infiltration and elevation of tattoos and old flat scars due to sarcoidosis. [2]: 710 Mucosal sarcoidosis is a cutaneous condition characterized by pinhead-sized papules that may be grouped and fused together to form a flat plaque. [2]: 711
The generally acknowledged theory proposes that a complex interplay among genetic predisposition, immunological dysregulation, and environmental factors leads to sarcoidosis. [3] It is believed that an augmented cell-mediated immune response to one or more undiscovered antigens is the cause of the granulomatous inflammation. [ 6 ]
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.
Public health experts are warning of a ‘quad-demic’ this winter. Here’s where flu, COVID, RSV, and norovirus are spreading
Studies in other animals or in humans did not show the same effect and there is no evidence showing FD&C Red No. 3 causes cancer in humans. That said, Vanessa Rissetto, R.D., ...
Testicular sarcoidosis can present as a diffuse painless scrotal mass or can mimic acute epididymo-orchitis. Usually, it appears with systemic manifestations of the disease. [3] Since it causes occlusion and fibrosis of the ductus epididymis, fertility may be affected. [4]
