4.Hepatocellular Adenoma and Focal Nodular Hyperplasia.
Korean Journal of Medicine 2013;84(3):325-332
Recent advances in imaging technologies have offered us a great chance to detect a variety of focal liver lesions. Accordingly, it is of paramount importance to determine whether these focal liver lesions are malignant or nonmalignant. Some benign hepatic tumors mimicking hepatocellular carcinoma typically develop from either regenerative or dysplastic/neoplastic processes. The most common benign hepatic solid tumors that are not of vascular origin include focal nodular hyperplasia and hepatocellular adenoma. A majority of patients with benign hepatic tumors are often asymptomatic and require no specific treatment. However, surgical resection may be infrequently needed for cases with clinical symptoms or malignant potential. This review will touch on the epidemiology, pathogenesis, clinical features, diagnosis, and management of focal nodular hyperplasia and hepatocellular adenoma.

5.Malignant Transformation of Nodular Hyperplasia in the Thyroid: A Case Report.

Thyroid carcinogenesis is traditionally thought to originate 'de novo'. However, it is debatable whether a malignant transformation can possibly arise from a benign thyroid nodule, as suggested for the malignant transformation of a thyroid adenoma. To the best of our knowledge, no studies have been performed addressing the malignant transformation of nodular hyperplasia in the thyroid gland. Here, we report a case of nodular hyperplasia with focally malignant degeneration.

Primary liver tumors are uncommon in childhood, with a relative frequency of 3% of childhood tumors. Seventy three cases of pediatric primary liver tumors which were operated on at single institution between 1986 and 2002 were reviewed. There were 37 cases of hepatoblastoma, 11 hepatocellular carcinomas, 6 undifferentiated (embryonal) sarcomas, and 1 mixed germ-cell tumor in malignancies. Benign tumors constitute only 24.6% of liver tumors, including 7 hemangioendotheliomas, 5 mesenchymal hamartomas, 3 congenital cysts, and one each with focal nodular hyperplasia and hemangioma. The common presenting clinical features were abdominal mass or abdominal distension. Anatomical hepatic resections were carried out in 38 cases, and non anatomical resections in 34 cases. One patient died of a direct result of hepatic resection(1.4%), and complication rate was 16.4%.

7.Focal Nodular Hyperplasia of the Liver: A case report.
Journal of the Korean Surgical Society 1997;52(2):294-298
During the past decades, a number of reports have described benign liver tumors in young women using oral contraceptives. The masses were usually found incidentally in physical examination or were identified as the source of a spontaneous intraperitoneal hemorrhage. Focal nodular hyperplasia(FNH) is the one of these benign tumor of the liver. We report a case of an incidentally discovered mass of FNH in a 46-year-old man which was incidentally discovered.

We present here the radiological findings of a rare case of multiple focal nodular hyperplasia that was associated with portal vein atresia and portopulmonary hypertension in a young woman. This case illustrates and supports the pathophysiological hypotheses that were previously proposed for the coexistence of these three abnormalities.

Focal nodular hyperplasia-like nodules (FNH-like nodules) are hypervascular lesions that occur in the cirrhotic liver. Histologically,they are similar to classical FNH in an otherwise normal liver. Radiologically, FNH-like nodules may mimic hepatocellular carcinoma (HCC), and they have been misdiagnosed as HCC based on radiological findings. Their pathogenesis and etiology are unclear, but they may arise from a local hyperplastic response to vascular alterations like classical FNH. Rarely, these nodules transform into malignant tumors and cause complications. We report the case of a 28-year-old man with multiple FNH-like nodules in congenital liver cirrhosis.

Focal nodular hyperplasia is a benign hepatic tumor mainly composed of nodules of hepatocytes and Kupffer cells separated by fibrous septa. In general, it is difficult to differentiate focal nodular hyperplasia and hepatocellular carcinoma on ultrasonography, conventional CT(computerized tomography), and angiography. But IV bolus CT is of particular value in the diagnosis of focal nodular hyperplasia because it can divide enhanced CT into early and late phase and can characterize tumor vascularity and analyze any intratumoral elements. In our case, it was seen as a hypoechoic mass lesion on ultrasonograpl'hy and hyperdense mass lesion on early-phase IV bolus CF and isodense mass, lesion on late-phase IV bolus CT. On angiography, hypertrophy of the feeding artery and tumor staining were well visualized. The patient underwent operation and the mass was pathologically confirmed to a focal nodular hyperplasia. We report the first case of focal nodular hyperplasia on IV bolus CT in Korea.
