Hepatic sarcoid resembling lymphoma

Abstract

Sarcoidosis is an inflammatory disease characterised by non-caseating granulomas that can affect any organ, although lung involvement is the most common. It is rare to find sarcoidosis isolated to extrapulmonary organs. We describe a case of extrapulmonary sarcoidosis with involvement of the liver in a man in his late 40s. His initial clinical history and investigations were more consistent with a diagnosis of lymphoma until a liver biopsy was performed revealing non-caseating granulomas more suggestive of a diagnosis of sarcoidosis. This patient had a history of young-onset ischaemic heart disease (IHD). We discuss the possible links between sarcoidosis, an inflammatory condition, and IHD, as well as the challenges to treating such patients with concurrent metabolic syndrome. This case also highlights the heterogeneous nature of sarcoidosis, with the diagnosis being important as prompt treatment can prevent complications of end-stage liver disease, including portal hypertension and cirrhosis.
