Gastric carcinoid presented as gastric outlet obstruction.
Carcinoids are solid tumors of entero-chromaffin origin classified as neuroendocrine amine precursor uptake and decarboxylation (APUD) cell tumors and are found throughout the gastrointestinal tract from the stomach to the rectum, with a predilection for the ileum. These tumors rarely occur in the stomach, constituting only 2% of gastric tumors and 3.3% of all carcinoid tumors of the gastrointestinal tract. Localization of gastric tumors can be done by ultrasonography, computed tomography, and magnetic resonance imaging, but endoscopic biopsy is required for confirmation; demonstration of neurosecretory granules on microscopy is the most specific feature. Early resection is the treatment of choice. Prognosis of noninvasive tumors <2 cm in size in terms of 5-year survival rate is 100%. The 5-year survival rate declines and prognosis becomes poor with increase in size and with involvement of serosa, perineural infiltration, and lymph node metastasis.
