Sarcoidosis:
Chapter: 12
A chronic disease of unknown etiology in which non-caseating granulomas occur in almost any organ of the body. The lung is the most frequently involved organ, and histologically one may see multiple non-caseating granulomas scattered in the interstitium of the lung. Sarcoidosis is a protean clinical disease, and follows an unpredictable clinical course, characterized by either progressive chronicity, or periods of activity interspersed with remission (sometimes permanent), that may be spontaneous or initiated by steroid therapy. It is most common in young, black women.
