#3315 Angiosarcoma is a rare and aggressive tumor of the Thyroid. Case Report

Introduction: Angiosarcoma(AS) of the thyroid gland is a rare(2-4% of all thyroid neoplasms) but highly malignant tumor with poor prognosis. AS showing endothelial differentiation. As most visceral ASs show epithelioid cell morphology, as well as co-expression of epithelial differentiation markers(keratins or EMA), the differential diagnosis with carcinomas is challenging. Given the importance of the correct histological diagnosis for therapy choice, this is a relevant issue

#3138 Prognostic value of expression SOX2 in neuroendocrine tumors of different localization and degree of malignancy

Introduction: Overexpression of the SOX2 gene is related to its amplification and with the multiplication of the copy number at the 3q26.3 gene locus on chromosome 3. It has been shown that the SOX2 transcription factor is a key regulator of pluripotency induction; it is involved in the reprogramming of terminally differentiated somatic cells.

#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.
