Also known as: Schaumann's Disease, Sarcoid of Boeck
Sarcoidosis is a multisystem disorder that most often affects individuals between 20 and 40 years of age. Females appear to be affected more frequently than males.

Sarcoidosis is characterized by the abnormal formation of inflammatory masses or nodules (granulomas) consisting of certain granular white blood cells (modified macrophages or epithelioid cells) in certain organs of the body. The granulomas that are formed are thought to alter the normal structure of and, potentially, the normal functions of, the affected organ(s), causing symptoms associated with the particular body system(s) in question. In individuals with sarcoidosis, such granuloma formation most commonly affects the lungs. However, in many cases, the upper respiratory system, lymph nodes, skin, and/or eyes may be involved. In addition, in some cases, other organs may be affected, including the liver, bone marrow, spleen, musculoskeletal system, heart, salivary glands and/or nervous system (i.e., central or peripheral nervous system).

Providence Pulmonary and Critical Care Medicine provides inpatient and outpatient consultation, evaluation and state-of-the-art treatment for a wide range of acute and chronic lung diseases and critical illnesses.
