Unable to process the form. These results show that some human pituitary adenomas may contain light bodies identical to those seen in gonadotrophs of rat pituitary The article presents two clinical cases of thyroid-stimulating hormone TSH-secreting pituitary adenomas in patients with different disease duration, and thus the presence of hyperthyroidism complications.

Ultrasound examination makes it possible microadenomw determine the shape, size, exact location of the node and its internal structure but gives no opportunity to udge its functional activity. At operation, the adenoma was found to be an intrathyroid and therefore a thyroid lobectomy was performed. The authors concluded that colonoscopy is the preferred miccroadenoma strategy and that improved access to colonoscopy is an important goal for occult blood screening programs.

Regular follow-up in the mean 6. Functioning and nonfunctioning thyroid adenomas involve different molecular pathogenetic mechanisms. Non- adenomas have conserved an ascending curve with the same delay. We also recorded relevant histopathological, demographic, clinical follow-up and survival data.
