#4605 Primary mammary neuroendocrine tumour: A case report and literature review

Introduction: Primary neuroendocrine carcinomas of the breast are rare, accounting for only 2 to 5% of all breast cancers. These tumours have recently been included in the latest WHO classification of breast tumours. The diagnosis can be challenging due to its uncommon presentation and overlap with other breast pathologies.

#4215 Breast neuroendocrine carcinomas surgery: A case report

Introduction: Breast carcinoma with neuroendocrine differentiation, also known as breast carcinoma (NEBC), (1) includes a heterogeneous group of rare tumors, which account for 2–5% of (2.3) all invasive breast carcinomas, less than 1% of neuroendocrine tumors. Large cell carcinoma of the breast represente < 0.1% of primary breast cancers; rarer than small cell carcinoma. Occur mainly in the 6th decade (2).

#3211 Microscopic resection margin status does not predict long-term survival in small bowel neuroendocrine tumors

Introduction: Small bowel neuroendocrine tumors (SBNETs) are increasing in incidence and are the most common small bowel malignancy. The characteristic nodal mass, which may extend high into the mesentery, can make achieving microscopically negative resection margins difficult without resecting excessive lengths of small bowel.

#2764 Cystic Pancreatic Neuroendocrine Tumors. Can We Diagnose Them Preoperatively?

Introduction: Pancreatic neueroendocrine tumors rarely undergo cystic changes but they are often misdiagnosed as pancreatic mucinous cystadenoma, mucinous cystadenocarcinoma, serous cystadenoma, and solid and cystic papillary tumors, or pseudocyst.
