Background: Inflammatory Pseudo Tumor (IPT)-like Follicular Dendritic Cell (FDC) Sarcoma of the liver is a very rare disease and occurs mostly in the lymph nodes. Till now, only 19 cases were reported in the English literature. However, the coexistence of IPT-like Sarcoma and Non-Hodgkin’s Lymphoma(NHL) in the same patient has never been reported.Case presentation: We reported a case of a 47-year-old male patient who had a history of Hepatitis B virus (HBV) infection and presented with right upper abdominal discomfort. Nineteen years ago, he underwent liver resection of segment VII for Hepatic Non-Hodgkin Lymphoma (B-cell lymphoma). Serum alpha fetoprotein (AFP) level was normal. However, Imaging studies revealed a well-circumscribed, solid mass in the right hepatic lobe and was diagnosed as (Hepatocellular Carcinoma) HCC or Hepatic Lymphoma preoperatively. Right hemi-hepatectomy was performed on this patient. Histological report showed features of a mixture of chronic inflammatory cells and variable amounts of spindle cells. Also, Immuno-Histo-Chemical (IHC) studies demonstrated that all the tumor cells showed strong nuclear in situ labeling for EBV-encoded small RNAs (EBER) and strongly positive stainings with CD21 and CD35. The patient is still disease free after a follow-up of 40 months. Conclusions: To our knowledge, this is the first report demonstrating Hepatic IPT-like FDC Sarcoma in a patient with Primary Hepatic Non-Hodgkin Lymphoma history. In regards to treatment, complete surgical resection should be performed and would acquire excellent long-term outcomes. |
