Introduction: Neuroendocrine tumors (NETs) represent uncommon neoplasms with different characteristics. They can be asymptomatic and benign or they can also proliferate and manifest themselves with neoplastic mass symptoms such as intestinal occlusion or with carcinoid syndrome. Gastric neuroendocrine neoplasms (g-NENs) are the most frequent digestive NENs while duodenal neuroendocrine neoplasms (d-NENs) may be sporadic or associated with multiple endocrine neoplasia type 1 (MEN-1) and present a functional syndrome (e.g. gastrinoma with Zollinger-Ellison syndrome). Presentation of case: We report a case of duodenal perforation due to a unknown gastrinoma responsible of Zollinger-Ellison Syndrome. He underwent an emergency contrast enhanced CT abdominal scan that showed a perforation. We performed a distal gastrectomy. The histopathological examination revealed a g-NET configuring a possible picture of Zollinger-Ellison Syndrome. Discussion: The management of NETs is diffulcult and controversial because of their rarity. It is useful to know the pathologic assessment of tumor differentiation and/or grade, evaluate surgical resectability and control the carcinoid syndrome symptoms. Conclusion: This case report shows that gastric NETs can be found in cases of duodenal perforation. Our future goal is to evaluate the possibilities to diagnose the Zollinger Ellison Syndrome as early as possible and to treat it with targeted therapy in order to prevent its related complications.

Abstract

Introduction: Neuroendocrine tumors (NETs) represent uncommon neoplasms with different characteristics. They can be asymptomatic and benign or they can also proliferate and manifest themselves with neoplastic mass symptoms such as intestinal occlusion or with carcinoid syndrome. Gastric neuroendocrine neoplasms (g-NENs) are the most frequent digestive NENs while duodenal neuroendocrine neoplasms (d-NENs) may be sporadic or associated with multiple endocrine neoplasia type 1 (MEN-1) and present a functional syndrome (e.g. gastrinoma with Zollinger-Ellison syndrome). Presentation of case: We report a case of duodenal perforation due to a unknown gastrinoma responsible of Zollinger-Ellison Syndrome. He underwent an emergency contrast enhanced CT abdominal scan that showed a perforation. We performed a distal gastrectomy. The histopathological examination revealed a g-NET configuring a possible picture of Zollinger-Ellison Syndrome. Discussion: The management of NETs is diffulcult and controversial because of their rarity. It is useful to know the pathologic assessment of tumor differentiation and/or grade, evaluate surgical resectability and control the carcinoid syndrome symptoms. Conclusion: This case report shows that gastric NETs can be found in cases of duodenal perforation. Our future goal is to evaluate the possibilities to diagnose the Zollinger Ellison Syndrome as early as possible and to treat it with targeted therapy in order to prevent its related complications.
