Compound gastroenteropancreatic neuroendocrine and gastrointestinal stromal tumors in the stomach: A case report.

Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) combined with gastrointestinal stromal tumors (GISTs) are rarely observed in the clinic. In the present study, the case of a 56-year-old female diagnosed with compound GEP-NETs and GISTs was reported. The patient initially presented with epigastric discomfort. The pre-operative diagnosis was of GISTs based on the endoscopic and imaging findings. A subtotal gastrectomy and Roux-en-Y reconstruction were successfully performed. The final diagnosis was revised to be compound GEP-NETs and GISTs based on the pathological findings. After 17 months of follow-up examinations using computed tomography and ultrasonography, the patient showed no symptoms or signs of recurrence.
