INTRODUCTION: Sarcoidosis is a granulomatous disease affecting multiple organs including but not limited to the lungs, heart, and skin. IL-2 is thought to be implicated in the pathophysiology of sarcoidosis; hence inhibitors of IL-2 production should theoretically reduce the incidence of sarcoidosis

CASE PRESENTATION: 62-year-old man with a history of hepatitis C virus (HCV) infection underwent an orthotropic liver transplantation in 2011 and presented 4 years later with worsening cough, dyspnea, and fatigue for 8 months. Additional symptoms included a macular rash on the knees, and a transient hemianopia. A PET-CT scan revealed multiple FDG-avid lymph nodes in the mediastinum and retroperitoneum and FDG-avid lesions in the left gluteal, subpleural, and bibasilar areas. An excisional biopsy of the left gluteal lesion revealed multiple non-caseating granulomas. Bronchoalveolar lavage and transbronchial tissue stains and cultures were negative for bacterial or fungal organisms. Transbronchial biopsy of the left lower lobe revealed non-necrotizing granulomas. Review of the pre-liver transplant liver biopsy did not reveal any granulomas. The patient was diagnosed with de novo pulmonary sarcoidosis with cutaneous involvement. The patient was started on prednisone 20 mg daily after which symptoms improved significantly on his first follow-up visit

DISCUSSION: To our knowledge, this is a rare case of de novo sarcoidosis involving the lungs and other extrahepatic organs despite inhibition of IL-2 with tacrolimus.Granulomas have been reported in both native and allograft livers of patients with chronic HCV infection but there has been no report of extrahepatic granulomas attributed to HCV. We postulate that HCV infection might be involved in an alternative immunologic pathway leading to the development of extrahepatic sarcoidosis

CONCLUSIONS: The incidence of de novo extrahepatic sarcoidosis after liver transplant is rare, but clinicians should be aware of this condition in this subset of patients
