#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.

#1267 Two Cases of Parathyroid Cancer with Pulmonary Metastasis
Introduction: Parathyroid cancer(PC) is a rare disease accounting for less then 1% of all patients with primary hyperparathyroidism. The prognosis of patients with parathyroid carcinoma is variable; more than 50% have a persistent or recurrent disease due to a regional or distant disease.

#2176 New MENIN Mutation Associated with Familial Isolated Hyperparathyroidism. Clinical Case of Three Young Sisters.
Introduction: The primary hyperparathyroidism (PHPT) is a sporadic disorder in the majority of cases, and only 5-10% of cases are associated with familial syndromes. The following familial syndromes associated with PHPT are known to date: multiple endocrine neoplasia type 1 (MEN1), type 2A (MEN2A), type 4 (MEN4), hyperparathyroidism-jaw tumor syndrome (HPT-JT), familial hypocalciuric hypercalcemia (FHH), neonatal severe hyperparathyroidism (NSHPT) and familial isolated hyperparathyroidism (FIHP). FIHP is defined as hereditary PHPT without the association with other diseases or tumors and may be caused by mutations in MEN1, HRPT2, or CASR genes.

#463 Primary Neuroendocrine Tumor of the Parathyroid
Introduction: Parathyroids are derived from third and fourth branchial pouches and neuroendocrine C-cells originate for neighboring fifth branchial pouch. A close ontogenic relation between these embryonal pouches is illustrated in DiGeorge syndrome wherein there is an absence of parathyroid glands and C-cells. It is not known for certain if normal parathyroids contain NE cells. However, NETs of the parathyroid have been reported in two other cases (Medline search: 1966-2011).

#35 Primary Hyperparathyroidism in patients with gastric carcinoid Tumors type-1: an unusual coexistence
Introduction: Although a number of familiar endocrine syndromes are associated with primary hyperparathyroidism (PHP), there is no information regarding its prevalence in other sporadic neuroendocrine diseases.

#263 Chronic Atrophic Gastritis Associated with Hyperparathyroidism: A prospective Study
Introduction: The association of gastric carcinoids (GCs) type 1 and hyperparathyroidism (HPTH) has been reported, whereas a possible association between chronic atrophic gastritis (CAG) and HPTH is still scant.

#157 Multiple Endocrine Neoplasia Type 1 (MEN-1), Hadassah-Hebrew University Medical Center experience
Introduction: MEN 1 is an autosomal dominant genetic disorder with a prevalence of 2-4 per 100,000. The main manifestations are parathyroid (PT), gastroenteropancreatic (GEP) and pituitary tumors, but may affect other organ systems as well. MEN 1 is associated with significant morbidity and mortality, with up to 50% dying before the age of 50. Treating MEN 1 patients presents a unique diagnostic and therapeutic challenge.

#492 Should Primary Hyperparathyroidism at Age Below 40 Years Always Lead to Search for MEN-1, Despite Presence of Other Plausible Explanations?
Introduction: A 30-year-old female patient with inherited osteogenesis imperfecta (OI) Type 1 was referred due to hypercalcaemia and suspicion of primary hyperparathyroidism (pHPT). She had serum ca2+ 1.56 mmol/L, serum parathyroid hormone 115 ng/ml (< 70), and pHPT was diagnosed, but no scan uptake. By exploratory neck surgery, all parathyroid glands were hyperplastic and 3 ½ parathyroid + thymus were removed. The HPT was hypothesised to be due to abnormal calcium metabolism from OI (J Endocrinol Invest 1999), although not described previously.

#981 Parathyroid Hormone-Related Peptide (PTHrP) Secretion by Metastatic Gastroenteropancreatic Neuroendocrine Tumors (GEP-NET): Clinical Features, Diagnosis, Management, and Long-Term Follow-Up
Introduction: There are a few large series of patients with parathyroid hormone (PTH)-related protein (PTHrP) secreting neuroendocrine tumors (NETs) causing severe hypercalcemia.
