[Atypical pituitary tumors].

The significant progress made in recent years, especially in the field of imaging procedures and immunocytochemistry, has caused great improvement in the identification and differentiation of less known pituitary tumours. Thyrotropin (TSH)-secreting adenomas constitute about 1-2% of all pituitary tumours and their presence leads to central hyperthyroidism. This condition is characterised by a diffuse goiter, elevated circulating levels of free thyroid hormones and a nonsuppressed serum TSH.
