#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

#74 Non-functioning pancreatic endocrine tumors: diagnostic criteria and surgical treatment

Introduction: Neuroendocrine tumors were considered rare tumors several years ago. Several reports published recently have observed increased incidence of NETs suggesting that NETs are more prevalent than previously reported. Non-functioning pancreatic endocrine tumors (NFPETs), better defined as non-hyperfunctioning, are characterized by the absence of clinical or biochemical evidence of hormone hypersecretion. From the clinical standpoint, NFPETs can be either occasionally encountered or manifest clinically similar pancreatic tumors. Since both NFPET treatment and prognosis significantly differ from that of ductal adenocarcinoma and other pancreatic malignant tumors, an accurate differential diagnosis is needed.
