Peripheral primitive neuroectodermal tumour (PNET) is a malignant mesenchymal tumour. Although PNETs can occur in numerous solid organs, it is an extremely rare tumour entity, specially involving the liver. We report a 19-year-old boy with Hepatitis B Virus (HBV) infection who was diagnosed with a primary PNET of the liver.
外周原始神经外胚层肿瘤（PNET）是一种恶性间充质肿瘤。尽管PNET可发生于多个实体器官，但它是一种极其罕见的肿瘤类型，尤其累及肝脏。我们报告一例19岁感染乙型肝炎病毒（HBV）的男孩，他被诊断为原发性肝脏PNET。
