The way it presents itself varies remarkably from case to case. In some patients, it is very short-lived and mild, whereas in others it can become a chronic, debilitating sickness. Usually it is self-limiting, meaning that is resolves on its own or does not progress. Many cases require no treatment. Sometimes, however, it progresses to the point of fibrosis, the formation of scar-like fibrous tissue, which pernamently impairs the ability of the affected organ to function.
Corticosteroids are the mainstay of therapy.
They help suppress the inflammation and prevent granulomas and fibrosis from forming. Sarcoidosis is characterized by the formation of what are known as granulomas. A granuloma is a small, granular inflammatory lesion. Granulomas are characterized by a nodular appearance and a unique cellular pattern that can be seen through the microscope. They can form on nearly any part of the body, internal or external.
