Cyclical Cushing's disease: two distinct rhythms in a patient with a basophil adenoma.

A 71-yr-old woman with clinical signs of Cushing's syndrome was studied continuously for an extended period after demonstration of a paradoxical response to dexamethasone. She proved to have a corticotroph cell adenoma of the pituitary which caused secretion of ACTH and cortisol in two distinct rhythms. One rhythm consisted of a period of 40 days of excess cortisol production, followed by a period of 60-70 days of normal production. During the period of excess cortisol production there was a second rhythm, consisting of peaks of cortisol production every 3-6 days with intervening troughs of normal cortisol production. Prolonged clinical remission followed transphenoidal surgery, but the pituitary still has the ability to provoke abnormal amounts of cortisol secretion, as occurred during a postoperative dexamethasone suppression test. The long duration of normal cortisol production phases in this patient demonstrates the difficulty in excluding Cushing's syndrome in patients with suggestive clinical symptoms but normal serum and urinary cortisol levels if these tests are measured for a single short phase of several days.

Cyproheptadine-induced remission of Cushing's disease due to pituitary basophil adenoma.

Serotonin is involved in the control of ACTH secretion, possibly by stimulating corticotropin releasing factor secretion from the hypothalamus. Cushing's disease seems to be due to defective hypothalamic regulation of ACTH release from the pituitary gland. Cyproheptadine is a potent antagonist of serotonin and has been used successfully in some patients with Cushing's disease, although, generally, in women without radiological evidence of pituitary tumors. We report the successful use of cyproheptadine in a 54-year-old man with Cushing's disease due to pituitary basophil adenoma. Significant clinical and biochemical improvement was noted 45 days after treatment began. The results in this patient support our findings that cyproheptadine can be effective in patients with Cushing's disease due to pituitary tumors, as well as in preparing very ill patients for surgery or managing such patients until radiotherapy takes effect.

Adenoma, Basophil↗

[Basophilic adenoma in combination with a prolapse of adenohypophyseal tissue through the capsule].

During the post-mortem examination of a 15-year patient who had died after the operation connected with incision of commissures a distorted form of the hypophysis was noted. Histological, histochemical and morphometric investigations showed that there was basophilic adenoma of adenohypophysis and prolapse of the tissue (beyond the borders of the adenoma) through a fistula against the background of changes characteristic of chronic diseases in childhood. Oxyphilic shift, moreover, was noted not only in the first zone of the adenohypophysis, but in other zones, as well as with a simultaneous increase in number of basophiles in I--III zones. Prolapse of the tissue, the latter being normal as far as the tumours growth was concerned, through the fistula took place at a considerable distance from the adenoma, which justifies the consideration of this process as a result of hyperplasia not connected with adenoma. Edges of the fistula bordering the prolapse, haemorrhages were to be seen.

Electroconvulsive therapy following pituitary surgery.

A 39-year-old female with a history of three psychotic episodes in 6 months developed Cushingoid features and catatonia. Despite the surgical removal of a pituitary basophil adenoma and treatment with neurleptics, her catatonia worsened. Electroconvulsive therapy provided rapid, life-saving relief for this patient. Patient characteristics are discussed and treatment recommendations provided.
