Lymphoepithelioma-like cholangiocarcinomas are rare tumors and most of them are related with Epstein-Barr virus (EBV) infection. Here, a case of a patient with lymphoepithelioma-like cholangiocarcinoma not associated with EBV infection is presented. In a 79-year-old man with hepatitis B virus-associated cirrhosis, a liver mass was detected on abdominal CT. Macroscopically, the resected tumor was pale gray, rubbery and well defined. Histologically, the tumor was composed of two components: an adenocarcinoma that formed irregular small glands and a lymphoepithelioma-like carcinoma that exhibited sheets of undifferentiated epithelial cells with lymphoid stroma. Lymphoplasmacytic infiltrates were more predominant in the lymphoepithelioma-like carcinoma than in the adenocarcinoma. Both components were roughly divided, but they gradually merged. Immunohistochemically, the adenocarcinoma component was diffusely positive for AE1/AE3, cytokeratin 7, cytokeratin 19 and epithelial membrane antigen, while the lymphoepithelioma-like carcinoma component was focally positive for them. However, both components were diffusely positive for p53 protein, and in situ hybridization using EBV-encoded RNA 1 was negative in both components as well. Examination of a resected para-aortic lymph node revealed metastasis exclusively of the lymphoepithelioma-like carcinoma component.

Prothrombotic haematological disorders, in particular myeloproliferative disorders, are identified in a significant proportion of patients with Budd-Chiari syndrome and portal vein thrombosis (PVT). Multiple prothrombotic disorders may coexist. PVT is diagnosed in one fourth of patients with cirrhosis and is more common with advanced liver disease and hepatocellular carcinoma. PVT in cirrhosis can precipitate decompensation. Intrahepatic microthrombosis may play a role in the pathogenesis of hepatic fibrosis. Sinusoidal obstruction syndrome is usually a complication of myeloablative treatment before haematopoietic stem cell transplantation. Post-transplant lymphoproliferative disorders can complicate liver transplantation and are related to Epstein-Barr virus infection. Hepatitis B reactivation in patients receiving chemotherapy for haematological malignancies is very common without pre-emptive treatment, and can lead to liver failure. Liver involvement is common in primary haematological diseases, such as haemolytic anaemias, lymphomas and leukaemia.

Spindle cell neoplasms are rarely reported in liver allografts; most are benign and associated with Epstein-Barr virus infection. We present a case of a malignant spindle cell neoplasm arising in a liver allograft. The patient underwent orthotopic liver transplant for cirrhosis secondary to nonalcoholic steatohepatitis. After 2 years, he presented with vague abdominal complaints. Imaging studies revealed a 10-cm right hepatic lobe mass. The patient underwent right-sided hepatectomy. The tumor displayed areas of broad, relatively hypocellular fascicles, whorls, and perivascular clustering; spindle cells with mild to moderate nuclear pleomorphism; and relatively abundant eosinophilic cytoplasm. Mitotic activity ranged from 2 to 4 mitotic figures per 20 high-power fields. Immunostaining displayed positivity for epithelial membrane antigen, vimentin, CD99, BCL2, cytokeratin, and human herpesvirus 8. Interphase fluorescence in situ hybridization findings were negative for a translocation involving the SS18 gene (18q11). We believe the tumor represents the first reported case of a novel unclassified spindle cell malignant neoplasm in a liver allograft.

Aim To describe a case of an eight-year-old boy with chronic Epstein-Barr virus (EBV) hepatitis with incipient cirrhosis, rarely found in practice. Methods The diagnosis was based on findings of specific IgG serum antibodies and EBV positive liver biopsy. Other etiologies of hepatitis were excluded: autoimmune hepatitis, viral hepatitis A, B, or C, cytomegalovirus (CMV), herpes simplex virus (HSV), adenovirus infection, toxoplasma infection. Results A mild form of infectious mononucleosis with acute hepatitis without icterus was found in the boy first time at the age of three. He got sick again in april 2018 with fever, minor loss of appetite and weakness, skin and sclera were anicteric, no enlarged neck lymph nodes. Ultrasonography of the spleen revealed a spleen diameter of 10.7 cm, while the liver was 11.8 cm. Laboratory findings, sedimentation, blood count, C reactive protein (CRP) were all normal. Ten days and a month later an increase of aminotransferase was noticed. The liver biopsy and PCR EBV DNA were performed six months of disease onset. The disease had lasted for about one more year with loss of strength and an increase of aminotransferase with maximum value of 3-4 times higher than normal one. The therapy was supportive. Conclusion Chronic EBV hepatitis is very rare. In differential diagnosis of hepatitis and unclear febrile conditions, EBV infection should not be forgotten.

Although indolent T-lymphoblastic proliferation (iT-LBP) in the extrathymic location have been shown to be a distinct clinicopathologic entity, carcinoma composed iT-LBP are rare. We retrospectively analyzed the clinicopathological features of 7 hepatic carcinoma cases with iT-LBP. There were 5 male and 2 female patients, aged from 37-54 (mean 47) years. All patients had a clinical history of chronic hepatitis B viral infection with high serum AFP level. Microscopically, these carcinomas were characterized by admixed with increased amounts of fibrous and small lymphocytes composed of regressive germinal centers. Immunohistochemically, in lymphoid tissues, some TDT+ cells were highlighted in the CD3+ area. These lymphoblasts localized predominantly between the cords of the carcinoma and interfollicular regions, diffused or only focal presented more than 50 TdT+ lymphoblasts/HPF. No EBV infection cells and T-cell antigen clonal rearrangement was detected. 3/4 cirrhotic patients developed HCC recurrence, while the 4-y survival rate was 100% in non-cirrhosis patients. It-LBP is a rare unusual proliferation and easily be misdiagnosed in HC patients. It does not seem to be associated with a specific HCC type. If HC companied with numerous small lymphocytes infiltration and showed high Ki67 index, a primary HC with iT-LBP should be considered in the lists of diagnosis.
