#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.

#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.

#1266 Three Cases of Ectopic Adrenocorticotropic Hormone Syndrome Due to Medullary Thyroid Carcinoma
Introduction: Сushing's syndrome (CS) in medullar thyroid carcinoma (MTC) is rare. Among patients with MTC 0,7 % developed ectopic ACTH-syndrome (EAS). EAS due to MTS occurs in 2,2-8% of cases.

Introduction: Cytokeratin 19 (CK19) is the marker of pluripotent cells of the epithelium of the pancreatic ducts, which is not detected in differentiated endocrine cells. Our experience shows that many patients with neuroendocrine tumors of the pancreas (pNET) G2 have a rapid progression of the disease a few years after diagnosis, and metastases are found most commonly in the liver.
