4B20.5/D86.3 Cutaneous sarcoidosis



The exact cause of cutaneous sarcoidosis is unknown. However, it is thought to be caused by an abnormal immune response to an infectious agent, such as a virus or bacteria.


Cutaneous sarcoidosis is usually diagnosed based on a combination of physical examination, medical history, and laboratory tests. These tests may include a skin biopsy, chest X-ray, and blood tests.

Differential diagnosis

Differential diagnosis of cutaneous sarcoidosis includes other skin diseases, such as psoriasis, eczema, and lupus.


Treatment of cutaneous sarcoidosis depends on the severity of the disease. Mild cases may require no treatment, but more severe cases may require medications such as corticosteroids or immunosuppressants.


The prognosis for cutaneous sarcoidosis is usually good, however, some cases may require long-term treatment. In some cases, the disease may recur after treatment has been stopped.
