AbstractAbstract PDF
Pituitary abscess is a rare pathology, but it is a potentially life-threatening condition. Therefore, timely intervention, including antibiotics and an operation, can prevent the morbidity and mortality in such cases. A 31-year-old woman, who was 16 months after her second delivery, presented with intermittent headache for 3 months. Amenorrhea, polyuria and polydipsia were noticed and the endocrinological hormone studies were compatible with panhypopituitarism and diabetes insipidus. Pituitary MRI demonstrated a 2.3 cm sized cystic mass with an upper small nodular lesion. Her symptoms such as headache and fever were repeatedly improved whenever corticosteroid was administered, which led us to suspect the diagnosis of an inflammatory condition like lymphocytic hypophysitis. During the hormone replacement therapy, her cystic pituitary mass had grown and her symptoms progressively worsened for another two months. The patient underwent trans-sphenoidal exploration and she turned out to have a pituitary abscess. At the 3-month follow-up, amenorrhea was noticed and her residual function of the pituitary was tested by a combined pituitary stimulation test. The results were compatible with panhypopituitarism. She received levothyroxine 100 microg, prednisolone 5 mg and desmopressin spray and she is being observed at the out-patient clinic. The authors experienced a patient with primary pituitary abscess that was confirmed pathologically and we report on its clinical course with a literature review.

AbstractAbstract PDF
Hypercalcemia is often observed in cancer patients secondary to parathyroid hormone (PTH) related peptide production. However, primary hyperparathyroidism and colon cancer rarely present simultaneously. Calcium is believed to have a chemopreventive effect against colorectal cancer because it reduces crypt cell hyperproliferation in both humans and in animals. There is evidence to suggest that the incidence of colorectal cancer in humans is reduced by high calcium intake. In patients with primary hyperparathyroidism, increased PTH activates 1,25(OH)2D and enhances calcium absorption in the gut. Consequently, the calcium level in the lumen is decreased, leading to an elevated risk of colorectal cancer. We report two patients with colon cancer and hypercalcemia secondary to primary hyperparathyroidism, along with a brief review of the literature.

AbstractAbstract PDF
We report a case of a 73-year-old female patient who was diagnosed with ectopic ACTH syndrome caused by small cell lung cancer. We initially presumed that the patient was in a state of mineralocorticoid excess, because she had hypertension and hypokalemic alkalosis. This was however excluded because her plasma renin activity was not suppressed and her plasma aldosterone/plasma renin activity ratio was below 25. Moreover, her 24 hour urine free cortisol level was elevated and her serum cortisol levels after a low dose dexamethasone suppression test, were not suppressed. Furthermore, her basal plasma ACTH and serum cortisol levels increased and her serum cortisol level after a high dose dexamethasone suppression test was not suppressed. We performed studies to identify the source of ectopic ACTH syndrome and found a 3 cm-sized mass in the patient's right lower lobe of her lung, which was eventually diagnosed as small cell lung cancer following a bronchoscopic biopsy. In conclusion, Cushing's syndrome, and in particular ectopic ACTH syndrome, must be considered in the differential diagnosis of mineralocorticoid-induced hypertension. The excessive cortisol saturates the 11beta-hydroxysteroid dehydrogenase type 2 (11beta-HSD2) activity, which in turn, inactivates the conversion of cortisol to cortisone in the renal tubules. Moreover, excessive cortisol causes binding to the mineralocorticoid receptors, causing mineralocorticoid hypertension, characterized by severe hypercortisolism.
