- The adrenocartical carcinoma is a rare tumor with an estimated incidence of 1 case per 1,700,000 population. Despite its rarity, a large number of investigators have studied this neoplasm for the following two reasons. The First is the occasional difficulty of differentiation between careinoma and adenoma at the time of initial surgery, even by histopathologic examination. The other is its unique feature of corticosteroidogenesis. Steroid metabolism of adrenocortieal carcinoma is characterized by its low efficiency of steroid production due to deficiency of steroidogenic enzyme. The deficieney of 11 B-hydroxylase has been indieated in case of adrenoeortical carcinoma by several investigators. In this study, the serum level of cortisol was within normal range, but the serum level of 11-deoxycortisol was 50 times higher than normal. After the removal of tumor, the serum level of ll-deoxycortisol was markedly decm. In conclusion, the results from the this case suggest that measurement of serum 11-deoxy- cortisol may be a useful tool in the diagnosis and follow-up of adrenocortical carcinoma.

Abstract

- Cushing's syndrome that is caused by an adenoma of the corticotrape cells of the anterior pituitay or, rarely, by couticotrope hyperplasia is refered to as Cushing's disease. Cushings disease is usually characterized by chronic, moderate hypersecretion of ACTH and other POMC derived peptide. Most patients have ACTH-secreting anterior pituitary corticotrope microadenomas, but a small minority have a pituitary macroadenoma. We recently experenced two cases of Cushings disease due to pituitary macroadenoma. and report this cases with review of literatures.

- This is a case report of a 61 years old man with suprasellar and pituitary metastasis from bronchogenic adenocarcinoma who developed polyuria and polydipsia. The clinical diagnosis has been made by bronchoscopy with washing cytology, biopsy of cervical lymph node, and brain MRI scan. Brain MRI scan showed metastatic tumor in the suprasellar area and pituitary gland with invasion of pituitary stalk. Light microscopic findings revealed adenocarcinoma in bronchoscopic washing cytology, and metastatic adenocarcinoma in the cervical lymph node. The combined pituitary stimulation test showed decreased reserve capacity of anterior pituitary hormones. And the water deprivation test also showed complete central diabetes inspidus. We report a case of suprasellar and pituitary metastasis from bronchogenic adenocarcinoma with a review of the literature.

Abstract
PDF
- Pheochromocytoma is originated from chromaffin cell of sympathetic nervous system and associated with other disease, such as neurofibromatosis, duodenal carcinoid, medullary thyroid cancer and parathyroid adenoma. Especially, pheochromocytoma is developed more than 50% in neurofibromatosis associated with hypertension. In such cases, several clinical features documented as more frequent bilateral phochromocytoma, more associated with other neuroendocrine tumors and thus more poor prognosis. We can observe the sustained hypertension despite of surgical resection of tumors in pheochromocytoma cases. One of the possible reason of post operative sustained hypertension is the pheochromocytoma originated from minor organ of Zukerkandl that was not resected during operation. Untreated or delayed treated cases with pheochromocytoma were often expired by complication of hypertension such as cerebrovascular hemorrhage, myocardial infarction, etc. Thus, in neurofibromatosis with hypertension, screening of pheochromocytorna is very important for the early detection of tumor and more favorable prognosis. Recently, We experienced a case of neurofibromatosis associated with bilateral pheochromocy-toma expired by cerebral hemorrhage during operation, so we report the case with literature review.
