Abstract

For a potentially malignant lymphadenopathy, it is clinically important to distinguish between metastasis of a primary tumor and a benign lesion such as systemic sarcoidosis or sarcoid reaction. We describe here a case of systemic sarcoidosis that was associated with early gastric cancer. A patient was found to have early gastric cancer (EGC) during routine clinical examination. The chest radiography demonstrated bilateral hilar lymphadenopathy and further examination showed that he had multiple lymphadenopathies. We diagnosed systemic sarcoidosis with EGC because of the elevated serum ACE-I, the chest CT findings and the pathological analysis. We performed endoscopic submucosal dissection (ESD) for EGC, and there was no local recurrence and distant metastasis for eighteen months. These findings suggest that the possibility of systemic sarcoidosis should be considered in cases with established malignancy and multiple lymphadenopathies.
