AbstractAbstract PDF
Multiple endocrine neoplasia type 1 (MEN 1) is characterized by the combined occurrence of primary hyperparathyroidism, enteropancreatic tumors and anterior pituitary adenoma. Yet carcinoid tumors, adrenal adenoma and lipoma might exist simultaneously. Thymic carcinoid tumors, which are recognized as one of the causes of death for patients with MEN 1, are uncommon and their natural history has barely been investigated.

AbstractAbstract PDF
Steroid 21-hydroxylase deficiency is the most frequent cause of congenital adrenal hyperplasia (CAH), which is an inherited inability to synthesize cortisol. Actually, CAH is caused by mutations in the CYP21 gene encoding the steroid 21-hydroxylase enzyme. In some cases, discordance has been observed between the genotype and the phenotype. We recently experienced two cases of simple virilizing congenital adrenal hyperplasia with compound heterozygous mutations of the CYP21 gene. The patients had primary amenorrhea and showed virilization. We have described these two cases along with a review of the literature.

AbstractAbstract PDF
BACKGROUND
Papillary thyroid carcinoma is among the most curable cancers, but some patients are at high risk for recurrence or even death. MHC antigens are essential molecules for the pathogenesis of carcinoma and also the physiologic immune responses against tumor. However, there is no data about the relationship between the expression of MHC antigens and the clinical prognosis of papillary thyroid carcinoma patients. METHODS: We analyzed the relationship between the various prognostic factors and the MHC antigen expression by conducting a retrospective study of 215 patients, who had undergone thyroidectomy for papillary thyroid carcinoma between 1987 and 2003. RESULTS: The expressions of MHC class II antigens were more frequent in papillary thyroid carcinoma than in the other thyroid diseases. Yet there was no statistically significant relationship between most of the clinicopathological factors and the expression of MHC class II antigens in papillary thyroid carcinoma patients. Interestingly, an HLA-DR expression was found in 8 (30.8%) of the 26 patients in the recurrence group and in 13 (76.5%) of the 17 patients in the non-recurrence group, and HLA-DP/DQ immunoreactivity was positive in 10 (38.5%) cases of the recurrence group and in 14 (82.4%) cases of the non-recurrence group. CONCLUSION: Papillary thyroid carcinoma showed a more frequent expression of MHC Class II antigens. However, the recurred papillary thyroid carcinoma showed a tendency to downregulate the expression of MHC class II antigens. Hence, the molecular mechanism for the expression of MHC class II antigens might have a role in the recurrence of papillary thyroid carcinoma.
