Neuroendocrine tumors, regardless of the type of hormone produced, have potential as cystic transformation. The case of women who presented 15 years ago 3 years accompanied mumps upper abdomen pain and vomiting. Studies were conducted to diagnose acute pancreatitis and abdominal CT with evidence of 3 lesions located one in the pancreas tail and one in considering the diagnosis of neuroendocrine injury. Gastrin twice the reported high levels of 970ng/L and 1313ng/L, is treated with proton pump inhibitors 40mg BID partially improve the symptoms. The patient did not attend regular checkups for consultation over a period of 2 years. In April this year was higher Ecoendoscopy to resubmit the same symptoms and showed 5 lesions in the pancreas of mixed characteristics internal structure micro cystic lesions suggestive of neuroendocrine. We performed EUS-guided aspiration of 3 lesions observed neoplastic epithelial cells, suggesting well-differentiated neuroendocrine tumors. The reported Immunohistochemistry positive for chromogranin, synaptophysin and neuron-specific enolase. Currently the patient is in surgical plan.
