#2218 More than Rare Pheochromocytomas: Bilateral and Hemorrhagic, Giant and Metastatic

Introduction: Pheochromocytomas (PCC) are rare neuroendocrine tumors. These catecholamine-secreting tumors, with an average size of 4.9cm, are multiple in 10% of cases. About 10% are malignant but distant metastases are rare. Non-traumatic adrenal hemorrhage is an unusual potentially fatal event seen in PCC.

#1720 Yttrium90 Radioembolization for Progressive Medullary Thyroid Carcinoma with Exclusive Liver Metastasis

Introduction: Medullary thyroid carcinoma (MTC) is a well-differentiated neuroendocrine tumor and accounts for 5-10% of all thyroid cancers. Distant metastases frequently involve the liver and patient’s survival after diagnosis is around 20% at 10 years

#782 Appendix Well-Differentiated Neuroendocrine Tumors (A-WDNETs) at a Large Tertiary Center: Clinical-Pathological Features and Long-Term Follow-Up Evaluation

Introduction: A-WDNETs comprise 32-57% of appendix tumors, diagnosed incidentally in 0.3-0.9% appendectomies (AP). Overall survival is good, but malignant behavior remains controversial.
