Sarcoidosis patients with acute arthritis often also have bilateral hilar lymphadenopathy and erythema nodosum. These three associated syndromes often occur together in Löfgren syndrome. [ 72 ] The arthritis symptoms of Löfgren syndrome occur most frequently in the ankles, followed by the knees, wrists, elbows, and metacarpophalangeal joints ...
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 peak incidence of sarcoidosis and testicular neoplasia coincide at 20–40 years and this is why most patients end up having an orchiectomy. However, testicular tumours are much more common in white men, less than 3.5% of all testicular tumours being found in black men. [ 6 ]
The World Association of Sarcoidosis and other Granulomatous Disorders, also known as WASOG is an organisation of physicians involved in the diagnosis and treatment of sarcoidosis and related conditions.
Löfgren syndrome is a type of acute sarcoidosis, [1] an inflammatory disorder characterized by swollen lymph nodes in the chest, tender red nodules on the shins, fever and arthritis. [2] It is more common in women than men, and is more frequent in those of Scandinavian , Irish , African and Puerto Rican heritage.
One study of 80 CVID patients found eight of these had sarcoidosis, suggesting as high a prevalence in CVID populations as one in 10. [7] Given that less than 10 percent of those with sarcoidosis will have neurological involvement, and possibly later on in their disease course, neurosarcoidosis has a prevalence of less than four per 100,000.

Crystalline inclusion with developing Schaumann body, polarized, in sarcoidosis. In pathology, Schaumann bodies are calcium and protein inclusions inside of Langhans giant cells as part of a granuloma. Many conditions can cause Schaumann bodies, including: Sarcoidosis, Hypersensitivity pneumonitis, and; Berylliosis.
The discovery that the gene defect in Blau syndrome involves the CARD15/NOD2 gene has sparked investigation into its function as part of the innate immune system. The innate immune system recognizes pathogen-associated molecular patterns, including bacterial polysaccharides such as muramyl dipeptide, via its pattern recognition receptors, such as NOD2, to induce signaling pathways that ...
