Abstract
Gastric neuroendocrine neoplasms (g-NENs) represent the most frequent digestive NENs and are increasingly recognized thanks to diffusion of upper gastrointestinal endoscopy.
g-NENs can be sporadic or associated with multiple endocrine neoplasia type 1 (MEN-1) and present with a functional Zollinger-Ellison syndrome.
We described a case of a 60 years old Caucasian male came to emergency room with diffuse abdominal pain and leukocytosis on blood tests.
At the level of the pyloric portion we found irregularly thickened walls associated with a small fluid collection and bubbles of free air. On exploratory laparoscopy we found a large perforation (about 5 cm of size) in the first duodenum portion.
Histological examination revealed a gastric NET perforation as a consequence of hypergastrinemia secondary to gastrinoma.
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.
