肝局灶结节增生诊治的研究进展

Focal nodular hyperplasia： a review of new progress in the diagnosis and therapy

肝局灶结节增生（FNH）是常见的肝脏良性结节性病。FNH具有极低的破裂和出血的可能性，罕有恶变的潜能。目前对FNH的病理学基础仍有一定争议。对于不典型的FNH如何准确诊断仍有相当的难度。本综述对近年来FNH诊治的进展做一总结。

Focal nodular hyperplasia （FNH） is one of the most common benign liver tumors. It has no potential for malignant transformation and an extremely low rate of rupture or hemorrhage. However, its nature and pathogenesis are still controversial. Accurately diagnosing atypical lesions of FNH based on clinical presentation and radiographic studies are still difficult. This review aims to analyze current literature of FNH and to discuss the new progress of pathologically and clinically relevant advice regarding diagnosis and management.
