METHODS: 231 patients with sarcoidosis were enrolled at a single institution. Organ involvement was determined in each patient using the WASOG SAS. Individual organ involvement was felt to be present if there was biopsy confirmation or either “highly probable” or “at least probable” organ involvement. The fourteen distinct areas of organ involvement were compared between race, gender and age (<40 year old and ≥40 year old) groups: lung, neurologic, non-thoracic lymph node, renal, cardiac, skin, eye, liver, bone marrow, spleen, bone/joint, ENT, parotid/salivary and calcium metabolism. The difference of organ involvement were analyzed by c2 test corrected by continuity if needed.
