[Follow-up of a pediatric prolactin-producing hypophyseal tumor]

At the age of 10 years a prolactin-producing pituitary tumor was diagnosed in a boy now aged 16 1/2 years. After surgical removal with a relapse after 1 year, a second surgical intervention and pituitary radiation were necessary. In the cause of further hyperprolactinemia, Pravidel treatment (Bromocriptine) was started with success. After 4 1/2 years medical treatment was discontinued for 1 week, but remains of active tumor tissue activity with increased prolactin concentrations were found, so that further treatment with Pravidel is necessary.
