Sarcoidosis and cancer may mimic one another, making the distinction difficult. Sarcoidosis of the lung is primarily an interstitial lung disease in which the inflammatory process involves the alveoli, small bronchi, and small blood vessels. Caution is recommended, as it only shows a general relation with physiological markers of the disease and the variation is such that it has limited applicability in individual assessments, including treatment decisions.

Although it may be disfiguring, cutaneous sarcoidosis rarely causes major problems. Pulmonary arterial hypertension occurs by two mechanisms in cardiac sarcoidosis: reduced left heart function due to granulomas weakening the heart muscle or from impaired blood flow. Development of scleral nodule associated with sarcoidosis has been observed. It also frequently causes an increase in 1,dihydroxy vitamin D, the active metabolite of vitamin D , which is usually hydroxylated within the kidney, but in sarcoidosis patients, hydroxylation of vitamin D can occur outside the kidneys, namely inside the immune cells found in the granulomas the condition produces.

Gamma-interferon produced by activated lymphocytes and macrophages plays a major role in the synthesis of 1 alpha, 25 OH 2D3. The gland is usually not tender, but firm and smooth. Dry mouth can occur; other exocrine glands are affected only rarely. Jaundice is rare. People with sarcoidosis often have immunologic anomalies like allergies to test antigens such as Candida or purified protein derivative. Peripheral lymphadenopathy is very common, particularly involving the cervical the most common head and neck manifestation of the disease , axillary, epitrochlear, and inguinal nodes.

This causes a wide variety of musculoskeletal complaints that act through different mechanisms. Additionally, in African Americans, who seem to experience more severe and chronic disease, siblings and parents of sarcoidosis cases have about a 2.

The exact mechanism of this relation is not known, but some evidence supports the hypothesis that this is a consequence of Th1 lymphokine prevalence. This paradoxic state of simultaneous hyper- and hypoactivity is suggestive of a state of anergy. The anergy may also be responsible for the increased risk of infections and cancer.

The regulatory T-lymphocytes in the periphery of sarcoid granulomas appear to suppress IL-2 secretion, which is hypothesized to cause the state of anergy by preventing antigen-specific memory responses. Sarcoidosis is characterized by the formation of non-caseous epithelioid cell granulomas in various organs and tissues.
