title: [Gastrinoma has an infrequent prevalence in pediatric age: a case report].
abstract: The authors present the clinical, laboratory and radiological findings suggestive ofgastrinoma in a patient 1 year and 9 months old. Laboratory tests obtained after fasting revealed elevated serum gastrin, supporting the suspected diagnosis of gastrinoma. In the endoscopy an elevated lesion with central depression was observed. The immunohistochemical examination revealed the benign nature of the tumor and the hyperplasia of argentaffin cells. Gastrinoma is a rare disease that predominantly affects young adults, but it must be considered in the pediatric group when clinical and laboratorial features of this disease are observed.
