The presence of concurrent adenopathy is virtually diagnostic. Although predominantly affecting the lung, sarcoidosis is a multisystemic disorder and can involve many different organ systems including the meninges, bone, eyes, heart and skin. Histologic diagnosis is usually quite readily made by transbronchial biopsy. This is true even if there is no radiographically detectable interstitial disease. Therapy for sarcoidosis is steroid administration.
Responses vary considerably from individual to individual.
Other individuals will have recurrent relapses and others will be steroid dependent for life and may go on to end stage fibrosis.
