Systemic evaluation of a potential cutaneous sarcoidosis patient

The diagnosis of sarcoidosis cannot be established by the presence of granuloma in a single organ, such as the skin. Therefore, the patient with potential cutaneous sarcoidosis should undergo a systemic evaluation for two reasons: to help confirm the diagnosis, and to identify other potential problems. This article reviews the recommended testing in patients with suspected or known sarcoidosis. The evaluation leads to a wide number of organs being assessed by either history, physical examination or routine laboratory investigations. The major organs routinely assessed are the lungs, the eyes, the liver and the heart.
