Gottron's syndrome is a rare skin disorder that is characterized by purple or reddish-purple plaques on the extensor surfaces of the extremities. These plaques are usually located symmetrically on the joints of the fingers, elbows, knees, etc.
The causes of Gottron syndrome are not completely clear. It is believed to be an autoimmune disease in which the body's immune system attacks its own tissues. Gottron syndrome often accompanies other autoimmune diseases such as scleroderma, dermatomyositis, and rheumatoid arthritis.
Diagnosis is based on the characteristic clinical picture. Additional tests, such as a skin biopsy and blood tests, can help confirm the diagnosis and rule out other conditions.
Treatment for Gottron syndrome is aimed at reducing inflammation and controlling symptoms. Nonsteroidal anti-inflammatory drugs, glucocorticosteroids, and immunosuppressants can be used. In some cases, symptoms go away on their own.
The prognosis for Gottron syndrome varies depending on the severity of the disease and the effectiveness of treatment. Timely diagnosis and therapy can prevent disease progression and complications. Regular examinations by a rheumatologist are recommended to monitor patients' condition.
