NEUROENDOCRINE TUMORS- A Case Series and Literature Review

Background: Neuroendocrine tumors (NET) are extremely rare and aggressive tumor. The annual incidence of clinically significant neuroendocrine tumors is approximately 2.5 -5 per 100000. Case Series: Here we report eight cases of neuroendocrine tumors of various anatomical sites which were diagnosed and treated at our institution from the time period of 2015-2016. The aim of this case series was mostly to determine the incidence, age, gender and primary site distribution of Neuroendocrine tumor at our institution. This study also helped us to evaluate the mode of treatment given according to site of Neuroendocrine tumor and also their follow up. Out of eight cases of neuroendocrine tumor three of them are from lung, one each from Urinary Bladder, Paranasal sinus, Pancreas, Mediastinum, Retroperitoneal site. Out of eight cases six were male and two were females. Conclusion: Neuroendocrine tumors are extremely rare tumors and have wide range of clinical presentation according to the site of involvement. Hence it is clinically challenging in context to diagnosis and treatment. According to the clinical presentations, histopathological subtypes, immunohistochemistry and radiological finding accurate diagnosis and classification is vital for management
