A Case Report of an Unclassified Hepatocellular Adenoma which was Successfully Treated by Laparoscopic Hepatectomy

Abstract

A 16-year-old woman with no history of using contraceptives or anabolic steroids presented to a local hospital with epigastralgia. Although abdominal USG revealed a hepatic lesion measuring 3 cm in diameter, the patient refused further investigation. After one year, the lesion increased to 5 cm in diameter. She was referred to our hospital for further study, and based on the findings of dynamic contrast-enhanced CT, the lesion was suspected as a hepatocellular adenoma. Laparoscopic partial hepatectomy was performed, and the lesion was finally diagnosed by histopathology as an unclassified hepatocellular adenoma. There has been no sign of recurrence until date, 2 years since the surgery. We have presented the case here, as pathologically proven unclassified hepatocellular adenoma is extremely rare.
