[Spontaneous regression of a large liver tumor with markedly elevated serum enzyme levels]

The case of a liver tumor of 10 cm diameter in a 32-year-old asymptomatic woman is described with markedly elevated liver enzymes in the serum (transaminases and alkaline phosphatase). The tumor corresponded to a focal nodular hyperplasia or a hepatic adenoma. The regression of this hepatic tumor over a time period of 18 months after discontinuation of oral contraceptives was observed as well as a complete normalisation of laboratory findings. It is concluded that conservative management after withdrawal of hormonal contraception my be the preferable treatment for hepatic adenoma and focal nodular hyperplasia.
