Rationale: Hepatic inflammatory pseudotumor (IPT)-like follicular dendritic cell (FDC) sarcoma is a very rare disease. Till now, only 19 cases were reported in the English literature. However, the coexistence of IPT-like sarcoma and non-Hodgkin lymphoma (NHL) in the same patient has never been reported. In this report, we presented a case of hepatic IPT-like FDC with hepatic NHL history of which both were successfully resected. Patient concerns: We reported a case of a 47-year-old male patient who presented with right upper abdominal discomfort. Nineteen years ago, he underwent liver resection of segment VII for hepatic NHL (B-cell lymphoma). He had a history of chronic hepatitis B virus infection. Serum alpha fetoprotein level was normal. However, imaging studies revealed a well-circumscribed, solid mass in the right hepatic lobe, he came back to the clinic because he was worried about a recurrence of the B-cell lymphoma. Diagnoses: Based on the patient's past medical history and magnetic resonance imaging results, and he was diagnosed as hepatocellular carcinoma or hepatic NHL preoperatively. Interventions: Right hemi-hepatectomy was performed on this patient. Outcomes: Histological report showed features of a mixture of chronic inflammatory cells and variable amounts of spindle cells. Also, immuno-histo-chemical studies demonstrated that all the tumor cells showed strong nuclear in situ labeling for EBV-encoded small RNAs and strongly positive stainings with CD21 and CD35. The patient tolerated the surgery well, recovered smoothly and he was discharged on postoperative day 7 (day 7). The patient is still disease free after a follow-up of over 50 months. Conclusions: To our knowledge, this is the first report demonstrating hepatic IPT-like FDC sarcoma in a patient with primary hepatic NHL history. In regards to treatment, complete surgical resection should be performed and would acquire excellent long-term outcomes.

Rationale Portal vein thrombosis is defined as any thrombosis that develops in the portal vein system. It is considered a very rare and extremely lethal complication of hepatopancreatobiliary surgery. Patient concerns Acute portal vein thrombosis after hepatectomy in patients with hepatolithiasisis very rare. Acute portal vein thrombosis is considered as a dangerous complication after hepatectomy. It is easy to ignore the symptom of acute portal vein thrombosis. Once the appropriate time of treatment is past, it would lead to patients' death. Diagnose Acute portal vein thrombosis after hepatectomy in a patient with hepatolithiasis INTERVENTIONS:: We consider anticoagulation therapy and percutaneous transhepatic portal vein puncture and thrombectomy once the diagnosis of acute portal vein thrombosis is confirmed. Outcomes The patient's liver function continued to deteriorate, eventually resulting in death. Lessons Acute portal vein thrombosis after hepatectomy is difficult to diagnose. The management of acute portal vein thrombosis remains controversial according to its severity, location or time of discovering.

The ideal surgical treatment of giant liver hemangioma is still controversial. This study aims to compare the outcomes of enucleation with those of resection for liver hemangioma larger than 10 cm in different locations of the liver and establish the preoperative predictors of increased intraoperative blood loss. Eighty-six patients underwent enucleation or liver resection for liver hemangioma larger than 10 cm was retrospectively reviewed. Patient demographic, tumor characteristics, surgical indications, the outcomes of both surgical treatment, and the clinicopathological parameters influencing intraoperative blood loss were analyzed. Forty-six patients received enucleation and 40 patients received liver resection. Mean tumor size was 14.1 cm with a range of 10–35 cm. Blood loss, blood product usage, operative time, hepatic vascular occlusion time and frequency, complications and postsurgical hospital stay were similar between liver resections and enucleation for right-liver and left-liver hemangiomas. There was no surgery-related mortality in either group. Bleeding was more related to adjacency of major vascular structures than the size of hemangioma. Adjacency to major vascular structures and right or bilateral liver hemangiomas were independently associated with blood loss >550 mL (P = 0.000 and 0.042, respectively). Both enucleation and liver resection are safe and effective surgical treatments for liver hemangiomas larger than 10 cm. The risk of intraoperative blood loss is related to adjacency to major vascular structures and the location of hemangioma.
