What is subcutaneous sarcoidosis?
Histologically, subcutaneous sarcoidosis is defined by the presence of non-caseating granulomas present in the subcutaneous tissue[6]. On ultrasound imaging these lesions present as an irregularly defined mass with hyper and hypoechoic areas[9].
How does a person get sarcoidosis?
The cause of pulmonary sarcoidosis is unknown. Experts think that bacteria, viruses, or chemicals might trigger the disease. It may also be genetic. This means a person is more likely to develop sarcoidosis if someone his or her close family has it.
Can pulmonary sarcoidosis be cured?
There is no cure for sarcoidosis, but most people do very well with no treatment or only modest treatment. In some cases, sarcoidosis goes away on its own. However, sarcoidosis may last for years and may cause organ damage.
What is Lofgrens?
Löfgren syndrome is a type of acute sarcoidosis, an inflammatory disorder characterized by swollen lymph nodes in the chest, tender red nodules on the shins, fever and arthritis. It is more common in women than men, and is more frequent in those of Scandinavian, Irish, African and Puerto Rican heritage.
Is sarcoidosis a serious illness?
In some people, the disease may result in the deterioration of the affected organ. When the granulomas or fibrosis seriously affect the function of a vital organ — such as the lungs, heart, nervous system, liver, or kidneys — sarcoidosis can be fatal.
What is the survival rate for sarcoidosis?
Survival was 84% at 10 yrs. Cause of death in 11% patients included refractory pulmonary hypertension, acute and chronic respiratory insufficiency, and heart sarcoidosis. Seventy-five percent of fatalities are directly attributable to respiratory causes.
What causes Lofgrens syndrome?
Löfgren syndrome usually resolves within six months to two years of diagnosis, sometimes without treatment. The exact cause of Löfgren syndrome, and of sarcoidosis in general, is not known. It is thought to involve a combination of genetic and environmental factors, such as allergens, viruses, or bacteria.
What is the life expectancy of someone with sarcoidosis?
Most people with sarcoidosis live normal lives. About 60% of people with sarcoidosis recover on their own without any treatment, 30% have persistent disease that may or may not require treatment, and up to 10% with progressive long-standing disease have serious damage to organs or tissues that can be fatal.
