A Case of Focal Nodular Hyperplasia of the Liver
Abstract
- Focal nodular hyperplasia (FNH) of the liver is a lesion of unknown pathogenesis, and is characterized by a well circumscribed region of hyperplastic liver parenchyma containing stellate fibrous scar. FNH is a rare disease occumng predominantly in women of child bearing age. Often it is incidentally observed during imaging procedures performed for some other reasons. Surgical resection of FNH is seldom required because of the benign nature of the lesion and its lack of significant complication, A 37-year old man was referred to our hospital for the evaluation of hepatic mass en abdomonal ultrasoncgraphy. Abdominal ultrasonography showed lobulated, well-defined and isoechoic mass on right lobe of the liver. After various imaging procedures, segmentectomy (segment V, VI) was performed. Gross findings showed well-circumscribed, 13cm sized mass with fibrous septa and pathologic findings showed areas of localized growth of mature hepatocytes and septal fibrosis. These findings were consistent with the characteristics of FNH. We report a biopsy proven case of FNH which is unusually large and found in a male patient, with a review of the literatures.
