Background/aims: A liver transplant is the preferred treatment for patients with end-stage liver disease, as it usually results in longterm survival. However, due to the use of chronic immunosuppressive therapy, which is necessary to prevent rejection, de novo cancer is a major risk after transplantation. The aim of this study was to assess the incidence of post-transplant malignancies in children after liver transplantations.
Materials And Methods: The study group consisted of 206 liver transplant recipients, with no history of cancer, including hepatocellular carcinoma, in two liver transplantation centers in Turkey between 1997 and 2015. Data were obtained from patient's data chart.
Results: In the study group, de novo cancer was diagnosed in 13 of the 206 patients. Post-transplant lymphoproliferative disease (PTLD) occurred in seven (53.8%) patients and other malignancies in six of the 13 patients. The types of PTLD were as follows: B-cell origin (n=2), Epstein-Barr virus (EBV)-related (n=2), T-cell origin (n=1), and Hodgkin's lymphoma (n=2). EBV DNA was isolated from seven patients, three of whom developed PTLD. The others developed Kaposi's sarcomas, Burkitt's lymphomas, cutaneous large-cell lymphomas, Hodgkin's lymphomas, and liver sarcomas.
Conclusion: After transplantation, immunosuppressive treatment is unavoidable, increasing the risk of malignancies. However, a close follow-up and periodic screening can reduce cancer-related mortality and morbidity.

Splenic steal syndrome (SSS) post liver transplant is a potential cause of graft dysfunction in the setting of peripheral hepatic arterial bed resistance and redirection of blood flow to a dominant splenic artery resulting in reduction of hepatic arterial inflow. We report utilization of balloon occlusion of the proximal splenic artery as an objective measure to confirm the diagnosis of SSS in a patient with orthotopic liver transplant followed by successful treatment with proximal splenic artery embolization using Gelfoam and Amplatzer vascular plug. Written informed consent for the publication of this case report was obtained from the patient.

Hepatocellular carcinoma (HCC) is one of the most common forms of primary liver cancer worldwide. Herein, we present a review article that provides a broad overview of the current landscape of HCC, including the etiology, potential risk factors, and molecular pathways that can serve as potential therapeutic targets. The risk factors tend to vary depending on the geographic distribution; hepatitis B-induced cirrhosis and HCC occur more frequently in Asia and Sub-Saharan Africa, whereas metabolic disorders are the culprits in Western Europe and the Americas.

Unlabelled: Sinusoidal obstruction syndrome (SOS) is a distinctive and potentially fatal form of hepatic injury that mainly occurs after hematopoietic-stem cell transplantation but also due to many other conditions including drug or toxin exposure. Recently, immune checkpoint inhibitors (ICIs) have revolutionised the treatment of many solid organ malignancies. Furthermore, as their use has become more widespread, rare toxicities have emerged.

Glycogen storage disease type Ia (GSDIa) is a rare inherited disorder resulting in potentially life-threatening hypoglycemia, metabolic abnormalities, and complications often requiring hospitalization. This retrospective database analysis assessed the complications, resource utilization, and costs in a large cohort of patients with GSDIa. We conducted a retrospective cohort study of GSDIa patients and matched non-GSDIa comparators utilizing the PharMetrics® Plus database.

Liver transplant may be necessary to manage infectious complications from severe structural biliary disease. In this report, we describe a 71-year-old woman with history of coil-embolized hepatic artery pseudoaneurysm who subsequently developed biliary obstruction resulting from coil erosion into the common hepatic duct. Resultant complications included recurrent cholangitis, bacteremia, and numerous hepatic abscesses.
