#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

Introduction: Ovarian carcinoid tumors are rare, often arising within a mature teratoma. No recent reevaluation of the immunophenotype of these tumors with new markers available has been performed.

#1402 Merkel Cell Carcinoma of Lymph Node Without Skin Primary Can - and Should - Be Distinguished from Others Metastatic Neuroendocrine Carcinoma

Introduction: Merkel cell carcinoma of lymph node without primary tumour (MCCNWP) is a rare tumour which can be misinterpreted as lymph node metastasis (LNM) from a high-grade neuroendocrine carcinoma (NEC) on histological examination. However, this distinction is crucial for therapeutic management.

#558 MANECs Among Colorectal Signet Ring Cell Carcinomas

Introduction: The mixed adenoneuroendocrine carcinomas (MANEC, WHO 2010) are neoplasms with heterogeneous morphology, whose mixed nature may be difficult to recognize.

#171 Transcription Factor Signature in Pancreatic and Duodenal Neuroendocrine Neoplasms

Introduction: We recently identified ISL1 as a marker for pancreatic neuroendocrine neoplasms (P-NENs). ISL1 as well as PDX1, CDX2 and NGN3 are transcription factors (TF) involved in pancreato-duodenal development.
