Introduction:
Sarcoidosis is a multisystem disease characterized by the presence of non-caseating granulomas in affected organs. Almost 70% of patients with a sarcoidosis reaction have hepatic involvement. However, evidence-based clinical management or treatment strategies for hepatic sarcoidosis are poorly defined. Here, we present a case of a resected hepatic sarcoidosis patient. Additionally, we review the relevant hepatic sarcoidosis literature and discuss the clinical management of hepatic sarcoidosis.
Presentation of case:
A 20-mm liver tumor of segment 8 was incidentally detected in a 64-year-old female. Radiological images resembled the enhancement pattern of cholangiocellular carcinoma. Thus, this lesion was assigned a preoperative classification of pT1N0M0 stage I according to the 7th Union for International Cancer Control guidelines. The patient underwent a partial liver resection. Histologically, the tumor contained sarcoidosis lesions indicated by a conglomerate of epithelioid granulomas with giant cells. These histopathological findings were consistent with the diagnosis of hepatic sarcoidosis.
Discussion:
Histopathological examination has been established as the definitive diagnostic tool for hepatic sarcoidosis. Therefore, liver biopsy or surgical resection of a liver tumor should be considered in cases that are difficult to preoperatively distinguish from malignant tumors.
Conclusion:
We present the case of a patient with surgically resected hepatic sarcoidosis that was difficult to preoperatively distinguish from cholangiocellular carcinoma.
