- Secondary diabetes mellitus caused by increased growth hormone secretion (GH) has well been known. There is a close association between glucose intolerance and GH secretion, and increased GH level itself probably worsens the blood glucose control and lipid profile by increasing glycogenolysis and / or gluconeogenesis and by suppressing lipase activity. We report a case of acromegaly with diabetic ketoacidosis as and hypertriglyceridemia-induced acute pancreatitis. A 38 year old male, previously diagnosed to have acromegaly and diabetes, presented with nausea, vomiting, diffuse abdominal pain and altered mentality. There was no history of drug or alcohol consumption, blood gas analysis showed severe acidosis and urinanalysis for ketone was positive. His serum blood glucose, amylase and lipase levels were 494 mg/dL, 331 U/L, and 1288 U/L, respectively (reference values: 70~110 mg/dL, 13~100 U/L and 13~190 U/L, respectively). The patient was diagnosed as having diabetic ketoacidosis and acute pancreatitis. With the serum concentration of triglyceride being 1488 mg/dL and the absence of any obvious precipitating factors, we considered hypertriglyceridemia to be the cause of acute pancreatitis. He was treated with continuous intravenous insulin infusion, lipid lowering agent, and fluid replacement. After conservative management, general condition gradually improved and his serum amylase, lipase and triglyceride levels were all normalized. GH level was not suppressed under 2 ng/mL during oral glucose loading test, and basal GH and IGF levels were 231 ng/mL and 29.5 ng/mL, respectively. Sella MRI showed a 3.7 cm sized pituitary mass. On the 55th day of admission, transsphenoidal surgery was performed. In immunohistochemical staining, the pathologic tumor specimen was proved to be GH positive pituitary adenoma. This is the first case reported in the English literature of an acromegaly presenting with diabetic ketoacidosis and acute pancreatitis

- BACKGROUND
Craniopharyngioma is a suprasellar or intrasellar epithelial neoplasm that occurs in both children and adults. It accounts for 1.2 to 3 % of intracranial tumors with an incidence of 0.5 to 2 cases per one million populations each year. Recently, it has been postulated that it may have two pathogenetically separate subtypes, which are adamantinous and papillary craniopharyngioma, and that their clinical features may be different. However, there are some disagreements in this postulation. Therefore, we studied 22 consecutive patients with craniopharyngioma to evaluate the differences in clinical features and MRI findings between two subtypes. METHODS: We studied 22 patients with histologically proven craniopharyngioma after surgery at Samsung Medical center from 1995 to 1999. Thirteen patients were male, and nine patients were female. The average age was 30 years, with a range from 1 to 58 years. We divided 22 patients into two histopathologically separate subtypes; adamantinous and papillary subtypes. We compared the clinical features and MRI findings of two subtypes by reviewing medical records. RESULTS: Out of 22 patients with craniopharyngioma, 19 patients had an adamantinous subtype and 3 patients had a papillary subtype. The adamantinous subtype occurred frequently in the fifth decade and below twenty years, while the papillary subtype occurred predominantly in forth and fifth decades. The adamantinous subtype located in suprasellar or intrasellar portion as well as extrasellar portion, while the papillary subtype was restricted to the suprasellar location. The average tumor size of the adamantinous subtype was 3.7 cm, with a range from 1.4 to 6.0 cm, which was larger than that of the papillary subtype (average size 1.8 cm with a range from 1.5 to 2.3 cm, p< 0.05). The adamantinous subtype was predominantly cystic, while the papillary subtype was predominantly solid (p< 0.05). There were no significant differences in the preoperative clinical features and the postoperative complications between two subtypes. CONCLUSION: The adamantinous subtype had two peaks of occurrence in the fifth decade and below twenty years, while the papillary subtype occurred predominantly in forth and fifth decades. The adamantinous subtype was larger and had cystic portion, while the papillary subtype was smaller and had solid portion. The preoperative clinical features and the postoperative complications between two subtypes seemed not to be different.

- Goiter is present in 25-50% of patients with acromegaly, which probably results from IGF- I stimulation of thyroid cell growth. These goiters are usually non-toxic but there have been well documented cases of co-existent hyperthyroidism and acromegaly. Graves disease with acromegaly has been rarely reported compared with the other type of hyperthyroidism due to increased tumoral secretion of TSH. We experienced a 44-year-old woman who presented with Graves disease and acromegaly. Basal serum GH and IGF-I concentrations were 10.8 pg/L and 571.82 ng/mL, respectively (reference value: (5 mg/L and 130-354 ng/mL, respectively). GH was not suppressed less than 2 pg/L during oral glucose loading test. GH was stimulated by TRH. Postcontrast sellar MRI demonstrated ovoid-shaped low signal intensity nodule measuring O.8 cm in diameter in left side of pituitary gland. Thyroid scan(131I) showed enlarged thyroid with increased radioiodine uptake (61.3%). Histologic examination showed acidophilic adenoma. GH and prolactin were positive on immunohistochemical staining. GH was suppressed less than 2.26 mg/L by oral glucose loading following operation. The patient has been followed with antithyroid drug(PTU) medication after operation(TSA).

Abstract

- The tumors containing ganglion cells are rare in the pituitary gland. These tumors are divided into two groups. The first group is the cases of mixed gangliocytoma-adenoma that contained both gangliocytoma and pituitary adenoma elements in the same tumor and the second group is those of gangliocytoma that contained only gangliocytoma element. Since the first description by Kiyono in 1926, 45 cases have been reported. The most common presentation of these tumors is acromegaly and the cases of Cushings disease and galactorrhea-amenorrhea also have been reported. In immunohistochemical study, hypothalamic-releasing hormones are stained in gangliocytoma cells and adenohypophyseal hormones are stained in adenoma cells. The releasing hormones stained in gangliocytoma element and the pituitary hormones stained in adenoma elements are usually closely related but unrelated cases also have been reported. We report a case of a 41 year-old lady with acromegaly which was diagnosed as mixed gangliocytoma-adenoma after surgical removal of the pituitary tumor.

- Large pituitary adenomas causing Cushings disease are uncommon, and usually present with mild manifestations of Cushings syndrome. Large adenomas may have rapid growth and quickly reach a size large enough to become clinically apparent. These tumors are more frequently invasive than microadenomas, their widespread extensions make radical surgical removal difficult and the ultimate clinical course malignant. We report a case of 37 year-old women presenting amenorrhea, weight gain, and moon face. Sellar magnetic resonance imaging(MRI) demonstrated a large lobulating tumor measuring 3.5cm in diameter, arising from sella turcica, extending up to suprasellar area and invading the cavernous sinuses. Transfrontal adenectomy was performed to remove a mass, but residual mass was remained after surgery. Subsequent external brain radiotherapy(total dose 5400cGy) was performed. Histology revealed an adrenocorticotrophin(ACTH) secreting pituitary adenoma. After treatment, her menstration was started, body weight was reduced, and moon face was disappeared.

- BACKGROUND
It assumed that plurihormonal pituitary adenomas in acromegaly, which were immunohistochemically stained with other pituitary hormones in addition to GH and prolactin, would be originated from poorly differentiated cells. Therefore, we speculated that they might have higher growth rates and worse prognosis than monohormonal adenomas. To verify this speculation, we analyzed the frequency of plurihormonal adenomas and compared the clinical parameters and radiological invasiveness between plurihormonal adenoma and GH-prolactin adenoma in acromegaly. METHODS: We studied 38 patients with acromegaly (22 males and 16 females, mean age 40.7 years) who were underwent surgical removal of pituitary adenomas by TSA from January 1995 to February 1998. We performed immunohistochemical staining in these tumors using avidinbiotin peroxidase complex method. An adenoma was considered as immunoreactive when above 50 percents of tumor cells were stained with anti-hormonal antibodies. Invasiveness of tumors were evaluated by preoperative MRI findings on the basis of Hardys classification. RESULTS: The frequencies of plurihormonal and GH-prolactin adenomas were 42% and 58%, respectively. Plurihormonal adenoma included an adenoma which was not stained with prolactin, but with GH and other hormones. Prolactin immunoreactivity was found in 97%(37/38) of the tumors. Immunoreactivities to FSH, ACTH, LH, and TSH were found in 37.8%, 13.1%, 2.6% and 2.7%, respectively. There were no significant differences in age, basal serum GH and IGF-1 concentrations between plurihormonal and GH-prolactin adenomas. There were also no significant differences in response to TRH & LH stimulation tests and somatostatin & bromocriptine suppression tests between two groups. There were no differences in radiological invasiveness between two groups (plurihormonal adenoma, grade I 2, grade II 3, grade III 7, grade IV 4; GH-prolactin adenoma, grade I 3, grade II 6, grade III 9, grade IV 4). CONCLUSION: Plurihormonal adenomas were 44% and immunoreactivity to prolactin was 97% in pituitary adenomas in acromegaly. There were no significant differences in clinical parameters and radiological invasiveness between plurihormonal and GH-prolactin adenomas in acromegaly.
