摘　　要：BACKGROUND Inflammatory pseudotumor-like follicular dendritic cell sarcoma(IPT-like FDCS)is rare with a low malignant potential.Hepatic IPT-like FDCS has similar clinical features to hepatocellular carcinoma(HCC),making it extremely difficult to distinguish between them in clinical practice.We describe the case of a young female patient diagnosed with HCC before surgery,which was pathologically diagnosed as IPT-like FDCS after the left half of the liver was resected.During 6 mo of follow-up,the patient recovered well with no signs of recurrence or metastasis.CASE SUMMARY A 23-year-old female patient with a 2-year history of hepatitis B presented to the Affiliated Hospital of Guizhou Medical University.She was asymptomatic at presentation,and the findings from routine laboratory examinations were normal except for slightly elevated alpha-fetoprotein levels.However,ultrasonography revealed a 3-cm diameter mass in the left hepatic lobe,and abdominal contrastenhanced computed tomography revealed that the tumor had asymmetrical enhancement during the arterial phase,which declined during the portal venous phase,and had a pseudo-capsule appearance.Based on the findings from clinical assessments and imaging,the patient was diagnosed with HCC,for which she was hospitalized and had undergone laparoscopic left hepatectomy.However,the tumor specimens submitted for pathological analyses revealed IPT-like FDCS.After surgical removal of the tumor,the patient recovered.In addition,the patient continued to recover well during 6 mo of follow-up.CONCLUSION Hepatic IPT-like FDCS is difficult to distinguish from HCC.Hepatectomy may provide beneficial outcomes in non-metastatic hepatic IPT-like FDCS.
