AbstractAbstract PDF
Ectopic adrenocorticotropic hormone (ACTH) syndrome is mostly associated with neuroendocrine tumors and small cell carcinoma of the lung. This syndrome of prostate cancer is rare and has been reported in only a few cases. We report a patient with ectopic ACTH production associated with metastatic prostate cancer. A 70-year-old patient with metastatic prostate cancer was admitted to our hospital with septic shock. He had a history of hormonal therapy and transurethral prostatectomy. Adrenocortical function was checked due to consistent fever and poor general condition, which revealed markedly increased levels of basal plasma ACTH and serum cortisol. The patient did not present typical signs of the Cushing's syndrome, however, hypokalemia and a history of hypertension were found. He died in days as a result of multi-organ failure. On pathology, the prostatectomy specimen showed a tumor composed of mixed populations of adenocarcinoma and small cell carcinoma. The tumor cells in the small cell component were positive for chromogranin and ACTH. Although neuroendocrine differentiation in prostate cancer is rare, etopic ACTH production should be considered in patients with prostate cancer as well as in clinical features of ACTH hypersecretion.

AbstractAbstract PDF
Parathyroid cysts, which can be divided into functional and non-functional cysts, are rare causes of primary hyperparathyroidism. A technetium-99m-methoxyisobutylisonitrile (99mTc-sestamibi) parathyroid scan is a sensitive diagnostic tool for the localization, although it sometimes shows a false-negative result. Here we report a case of presumed cystic parathyroid adenoma based on clinical findings and analysis of cystic fluid with negative findings in a parathyroid scan. A 44-year-old male patient visited the hospital due to leg pain and compressive symptoms (dysphagia, hoarseness) that had started 4-5 months before. His serum calcium level was 14.4 mg/dL and his intact parathyroid hormone (iPTH) had increased to 478.1 pg/mL. On neck computed tomography, a cystic nodule measuring 6.2 cm was detected in the inferior part of the right thyroid gland. Sestamibi uptake for this nodule was not detected on 2-h delayed imaging, and fluorodeoxyglucose positron emission tomography showed only subtle uptake. Fine-needle aspiration was performed and intracystic iPTH had increased to 61,600 pg/mL. Focused parathyroidectomy guided by intraoperative iPTH monitoring led to successful enucleation of the right inferior parathyroid gland. A parathyroid adenoma was confirmed, and his laboratory results had normalized. This study shows that cystic parathyroid adenoma can sometimes be difficult to detect on a 99mTc-sestamibi parathyroid scan.

AbstractAbstract PDF
BACKGROUND
The objective of this study is to demonstrate the relationship between the volume of a parathyroid adenoma and the preoperative biochemical parameters in patients undergoing surgery for primary hyperparathyroidism. METHODS: The medical records of 68 patients who underwent a parathyroidectomy for a single parathyroid adenoma were retrospectively reviewed. The volume of the adenoma was estimated using its measured size and a mathematical formula. The correlation between the volume of the parathyroid adenoma and the preoperative laboratory data was assessed. RESULTS: There were no correlations between the estimated volume of the adenoma and the serum calcium, alkaline phosphatase and parathyroid hormone levels. However, the volume of the adenoma was associated with the preoperative level of serum phosphorus. After excluding 5 adenomas with cystic degeneration, a positive correlation was noted between the adenoma volume and the preoperative levels of alkaline phosphatase and parathyroid hormone. CONCLUSION: The preoperative serum levels of calcium, alkaline phosphatase and parathyroid hormone are of limited use to predict the volume of the parathyroid adenoma in patients with a single parathyroid adenoma. We suggest that the absence of a correlation between the volume of the adenoma and the biochemical parameters can be attributed to the cystic degeneration of the adenomas.
