#2156 Two Cases Synchronous Atypical Parathyroid Adenomas and Papillary Thyroid Carcinoma

Introduction: A literature review revealed a prevalence of approximately 3% of nonmedullary thyroid cancer, which was found in patients operated on for primary hyperparathyroidism (pHPT). Papillary thyroid carcinomas(PTC) is a malignant epithelial tumour. PTC represent up to 87% of all thyroid carcinomas. Atypical parathyroid adenoma(APA) are a subset of parathyroid neoplasms that exhibit some of the features of parathyroid carcinoma but lack unequivocal invasive growth. APA represents about 0,5-4% of cases of pHPT. As a group, they may be considered tumors of uncertain malignant potential.

#1689 The Prognostic Value of the Expression of Cytokeratin 7 and 19 in Lungs and Pancreas Neuroendocrine Tumors

Introduction: The expression of cytokeratins (CK) 7,19 rarely occurs in the low grade neuroendocrine tumors (NET) of lung and pancreas. It is known that part of the low grade typical (TC) and atypical (ATС) carcinoids of lung and pancreas (pNET-G1,G2) can progress quickly and to metastasize. It is important to distinguish NET with a less differentiated cells immunophentype.

#1641 Somatostatin Receptor Expression in Adrenocortical Carcinoma

Introduction: Adrenocortical carcinoma (ACC) is an uncommon neoplasm with an estimated annual incidence of 0.5-2 cases per million population. Surgery of the adrenal tumor is the major treatment. When complete tumor removal is not possible, or in case of recurrence, medical treatment with O,p’DDD(mitotane) is recommended. The treatment of ACC is currently based on the mitotane partial responses have been described in 19-34% of cases, and there are single reports of complete responses.The discovery of somatostatin (SST) and the identification of stable SST analogs with a longer half-life have raised new hopes for the treatment of endocrine tumors.
