#4172 Hormonally characterised NF-PanNETs and their clinicopathological features

Introduction: PanNETs show pronounced hormonal heterogeneity. The expression of certain hormones may associate with functional syndromes, but also with histological and genetic features. However, detailed studies of hormonal patterns in PanNETs correlated to morphological and clinical data are lacking.

#3427 Updated morphological and immunohistochemical profile of neuroendocrine tumors developed in ovarian teratomas: A large series of a rare disease

#3321 Calcitonin secreting neuroendocrine neoplasms of the lung: A systematic review

Introduction: Calcitonin (CTN) secreting neuroendocrine neoplasms (NEN) of the lung are rare, with few cases reported in the literature. Differentiating between medullary thyroid carcinoma (MTC) and ectopic source of calcitonin secretion can represent a complex diagnostic conundrum for managing physicians with cases of unnecessary thyroidectomy reported in the literature.

#2732 Prostate Metastasis of Medullary Thyroid Carcinoma in a Young Patient with MEN2B Syndrome

Introduction: Multiple Endocrine Neoplasia 2B is associated with particularly early onset medullary thyroid carcinoma (MTC). Metastatic MTC is the leading cause of early death in MEN2B. The usual sites of metastasis are neck, mediastinum, lung, liver, bone and brain.
