Abstract
Case summaries of four patients with bilateral hilar lymphadenopathy (BHL) caused by metastatic renal cell carcinoma are presented, and these and eight similar cases from the literature are analyzed. In nine patients, sarcoidosis was the provisional clinical diagnosis, but four of these patients had a past history of renal cell carcinoma. In the remaining five patients, a distinction from sarcoidosis could not be made by history, physical examination, and chest roentgenogram. This underscores the need for tissue confirmation in the diagnosis of sarcoidosis and alerts the physician to consider metastatic renal cell carcinoma in the differential diagnosis of BHL.
