By no means is Sarcoidosis limited to any one race or only those who practice a particular religion, or are in a certain age group or specific gender. It does not limit itself to an single organ or group of organs. It is universal throughout the world and throughout the body. It does not even restrict itself to hu-mans.
Veterinarians see it often in the equine population.
Sarcoidosis is a systemic granulomatous disease that primarily affects the lungs and lymphatic systems of the body. It can affect more than one organ at any time. Reaching a diagnosis continues to be one of medical detective work. A diagnosis of the disorder usually requires the demonstration of typical lesions in more than one organ system and exclusion of other disorders known to cause granulomatous disease. Jonathan Hutchinson first described skin lesions in 1877, Caesar Boeck gave the disease its name, Sarcoid.
