[The prolactin and TSH response to stimulation in patients with hypophyseal tumors].

The authors examined the prolactin (PRL) and thyrotropin (TSH) response to stimulation with chloropromazine and thyreoliberin in 10 patients with pituitary tumours. They observed a hypothalamic response instead of the expected pituitary response. These findings may be of importance for the understanding of the aetiopathogenesis of pituitary tumours. As we are able to influence nowadays some expansive pituitary processes by conservative treatment, these findings may in the near future be important in clinical practice.
