[Focal nodular hyperplasia--mixed liver cell and bile duct adenoma]

Although benign tumorous lesions of the liver are rare, they can be found particularly among women in the preclimacteric age group. Usually, the clinical findings are non-characteristic. Differentiation from other space-occupying growths can be difficult due to the variable appearance of focal nodular hyperplasia. The selective angiogram is typical in some cases and no further radiological procedures are required. Nevertheless, histological examinations should be performed for complete clarification.
