Disseminated Sarcoidosis Presenting as Granulomatous Gastritis

Commonly considered a pulmonary disease, sarcoidosis is actually a multisystemic granulomatous disorder of unclear etiology. There is a wide range of organ system involvement, with gastrointestinal being among the rarest. We describe the diagnostic challenge of a patient presenting with gastritis without pulmonary complaints who was later found to have extrathoracic disseminated sarcoidosis. This case highlighted both the variability in the presentation of the disease and difficulties in its diagnosis. We performed a literature review to identify studies published on gastrointestinal and hepatic sarcoidosis to better understand the characteristics of this disease and help in the differentiation between other commonly encountered disorders that may be mimicked in presentation. We have also created a diagnostic approach that can be applied when endoscopic or hepatic biopsies reveal granulomas. We anticipate that this review may be useful for clinicians who face these diagnostic dilemmas and management decisions for this complex and variable condition.
