Abstract
A diagnosis of sarcoidosis was evoked in a 61-year-old man on clinical and histologic bases. Nevertheless, a bile duct carcinoma was disclosed in association with the discovery of generalized sarcoid-like granulomas. This is only the third time that such an association has been described. HLA-B8, DR3, and DRw52 antigens were found, suggesting that altered immunologic mechanisms could play a role in the pathogenesis of this sarcoid-like reaction.
