Sarcoid

Sarcoid is a special form of skin lesions that occurs during sarcoidosis, a chronic systemic disease of unknown etiology, characterized by the formation of epithelioid cell granulomas in various organs without necrosis.

Skin sarcoids are dense, painless nodules or plaques of pinkish-red color, usually round in shape. The size of sarcoids varies from a few millimeters to several centimeters. Most often they are localized on the face, neck, upper chest and back, and limbs.

Additionally, the term "sarcoid" is sometimes used to refer to a rare, benign smooth muscle cell tumor that can arise in the soft tissue of various parts of the body.

Sarcoidosis is a rare disease characterized by fever and formations in various organs and tissues. No one knows its exact cause, but based on research, it is believed that it is an infection caused by microbacteria. It was first noticed in South Africa, so the disease was named in Arabic. At first it was believed that the disease was only a skin type, but then they discovered lesions in the eyes, lungs and internal organs. There are several subtypes of this infection:

Perivascular sarcoidosis. It manifests itself only in formations that surround large vessels. These formations are called sarcoids. The perivascular form is not accompanied by an influx of temperature, and even if sarcoid appears for the first time, it is common, and the temperature rises after the disease progresses. Alveolar sarcoidosis. With this form, the fever rarely rises, so the symptoms last a long time. But this is the most dangerous subtype, which leads to damage to internal organs. Usually 50% of patients die from it. Mixed or systemic sarcoidosis, in which all types of the disease are associated.
