Introduction: Lymphocytic hypophysitis(LH) is a rare autoimmune endocrinopathy that causes pituitary gland inflammation, resulting in hypopituitarism. Headache is the most common presenting symptom; however, diabetes insipidus (DI) may be the first feature in some patients. Here we report one such case. Case: a 36-year-old female was referred to the Endocrine clinic with sudden onset of polydipsia, polyuria and nocturia. She also reported amenorrhoea but...

Annexin-1 (ANXA1) is a 37 kDa calcium- and phospholipid-binding protein expressed abundantly in S100-positive folliculostellate (FS) cells in the anterior pituitary gland. ANXA1 is localised both intracellularly and on the cell surface in high density foci appearing at points of contact between the FS cells and the neighbouring secretory cells, where it has been demonstrated to mediate the glucocorticoid-induced negative feedback on the secretion of ACTH from corticotrophs. Gl...

Pituitary adenomas and phaeochromocytoma/paragangliomas (PHAEO/PGL) can very rarely occur in the same patient or in the same family. Together, they are not known to be part of any classical endocrine neoplasia syndromes. In some caes the pathogenetic mechanism may be secondary to a PHAEO secreting GHRH leading to somatotroph hyperplasia and clinical acromegaly. However, we suggest several other mechanisms which could lead to the development of pituitary and PHAEO/PGL together:...
