Purpose The molecular mechanisms underlying tumor growth in Cushing’s disease (CD) still remain a challenge. Moreover, clinical manifestations of CD may vary depending on hormonal activity; however, factors involved in the hormonal aggressiveness of adrenocorticotropic hormone (ACTH)-secreting pituitary tumors have not been fully clarified. We investigated the association between the expression of...
Fugitive acromegaly is most commonly caused by pituitary acidophil stem cell adenomas, and is characterized by a relatively short clinical history, a large and locally invasive tumor, and relatively low hormonal activity. Here, we report an unusual case of fugitive acromegaly that initially presented as invasive prolactinoma. A 48-year-old man with a huge pituitary mass extending to the suprasellar...
The objective of this study was to evaluate characteristics that discriminate prolactinoma from non-functioning pituitary macroadenoma with hyperprolactinemia. We included 117 patients with hyperprolactinemic pituitary macroadenomas. Patients were divided into three groups according to treatment outcomes and pathologic results: (A) prolactinoma that responded to dopamine agonist (DA) treatment (PRDA);...
