What is Sarcoidosis? Causes, Sign and symptoms

What is Sarcoidosis?

Sarcoidosis is the growth of tiny collections of inflammatory cells in different parts of your body — normally the lungs, lymph nodes, sight and skin.

Sarcoidosis was first identified over 100 years ago by two dermatologists working independently, Dr. Jonathan Hutchinson in England and Dr. Caesar Boeck in Norway. Sarcoidosis was originally called Hutchinson’s disease or Boeck’s disease. Dr. Boeck went on to fashion today’s name for the disease from the Greek words “sark” and “oid,” meaning flesh-like. The term describes the skin eruptions that are frequently caused by the illness.

Doctors believe sarcoidosis results on the body’s immune system answering an unknown substance, possibly something inhaled from the environment. There is no treatment for sarcoidosis, but most people prosper with modest treatment. Sarcoidosis often goes away alone. Alternatively, signs and symptoms regarding sarcoidosis may last for some time and sometimes lead to help organ damage.

As Sarcoidosis progresses, microscopic lumps of a selected form of inflammation, referred to as granulomas, appear in the affected tissues. In the majority of cases, these granulomas solve, either with or with no treatment. In the few cases the spot that the granulomas do not recover and disappear, the tissues usually remain inflamed and turn into scarred (fibrotic).

Normally, your defense mechanisms helps protect your human body from foreign substances along with invading microorganisms, such while bacteria and viruses. However in sarcoidosis, some immune cells collect within a pattern of inflammation known as granulomas. As granulomas build-up in an organ, the function of that organ can be impacted.
