Sarcoidosis (also known as Besnier-Boeck-Schaumann disease) is a disease involving abnormal collections of inflammatory cells that form lumps known as granulomata. The disease usually begins in the lungs, skin, or lymph nodes. Less commonly affected are the eyes, liver, heart, and brain. Any organ, however, can be affected. The signs and symptoms depend on the organ involved. Often, no, or only mild, symptoms are seen. When it affects the lungs, wheezing, coughing, shortness of breath, or chest pain may occur. Some may have Löfgren syndrome with fever, large lymph nodes, arthritis, and a rash known as erythema nodosum.The cause of sarcoidosis is unknown. 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. Those with affected family members are at greater risk. Diagnosis is partly based on signs and symptoms, which may be supported by biopsy. Findings that make it likely include large lymph nodes at the root of the lung on both sides, high blood calcium with a normal parathyroid hormone level, or elevated levels of angiotensin-converting enzyme in the blood. The diagnosis should only be made after excluding other possible causes of similar symptoms such as tuberculosis.Sarcoidosis may resolve without any treatment within a few years. However, some people may have long-term or severe disease. Some symptoms may be improved with the use of anti-inflammatory drugs such as ibuprofen. In cases where the condition causes significant health problems, steroids such as prednisone are indicated.
Etymology
The word "sarcoidosis" comes from Greek [σάρκο-] sarco- meaning "flesh", the suffix -(e)ido (from the Greek εἶδος -eidos [usually omitting the initial e in English as the diphthong epsilon-iota in Classic Greek stands for a long "i" = English ee]) meaning "type", " resembles" or "like", and -sis, a common suffix in Greek meaning "condition". Thus the whole word means "a condition that resembles crude flesh". The first cases of sarcoïdosis, which were recognised as a new pathological entity, in Scandinavia, at the end of the 19th century exhibited skin nodules resembling cutaneous sarcomas, hence the name initially given. Society and culture
The World Association of Sarcoidosis and Other Granulomatous Disorders (WASOG) is an organisation of physicians involved in the diagnosis and treatment of sarcoidosis and related conditions. WASOG publishes the journal Sarcoidosis, Vasculitis and Diffuse Lung Diseases. Additionally, the Foundation for Sarcoidosis Research (FSR) is devoted to supporting research into sarcoidosis and its possible treatments.There have been concerns that World Trade Center rescue workers are at a heightened risk for sarcoidosis.Comedian and actor Bernie Mac had sarcoidosis. In 2005, he mentioned that the disease was in remission.
