ABSTRACT
El síndrome de Zollinger Ellison es una entidad producto de un tumor neuroendocrino hipersecretor de gastrina, que genera acidez gástrica exagerada. Entre el 60 a 90% de los casos se comparta de forma maligna, se observan nódulos metastásicos en 50 a 67% de los casos, y se localizan principalmente en el denominado triángulos de los gastrinomas. Los métodos de imagen convencionales poseen poca sensibilidad en la detección de éstas lesiones, sobre todo para las menores a 1 cm. La endosonografía conjunto a la cintilografía de receptores de Somatostatina, son los métodos de imagen estándar de oro para diagnosticar estas lesiones. Presentamos el caso de un paciente masculino de 57 años, que consultó con pancreatitis aguda, enfermedad ulceropéptica y diarrea, a quien se detectó y estadió una lesión única mediante endosonografía, recibió tratamiento quirúrgico de forma exitosa...
Zollinger-Ellison syndrome is a disorder caused by a gastrin hypersecretory neuroendocrine tumor which produces severe gastric acidity. In 60% to 90% of the cases it`s malignant; metastatic nodules are observed in 50% to 67% of the cases, and are located primarily in the so called Gastrinoma triangle. The conventional imaging methods have poor sensibility in detecting these lesions, especially for those that are less than 1 cm. The endosonography conjoint with the Somatostatin receptors scintillography are the standard imaging gold methods to diagnose these lesions. We report the case of a male 57 years-old patient who came to consult with acute pancreatitis, peptic ulcer disease and diarrhea. By endosonography we detected and staged a single lesion. He received surgical treatment successfully...

Multiple endocrine neoplasia (MEN) is a rare familial disorder that affects multiple endocrine organs. it is inherited in an autosomal dominant pattern with variable penetrance. There are two distinct types of MEN. Dominantly inherited neoplasia are believed to occur from the recessive loss of tumor suppressor gene function. The first mutational event affects the germ cell, is hereditary, and predisposes to neoplasia. Because tumors occur in multiple organs in MEN, the second mutational evento probably occurs in common precursor cells, such as the amine precursor uptake and decarboxylation cells (APUD). The gene locus for tupe 1 MEN has been mapped to cromosome 11q. Type 1 organs affected: parathyroids, pancreas and pituitary. The gene locus for type 2 MEN is thought to be located for chromosome 10, (other organs). Fifty to 60 % of patients with type 1 MEN have pancreaticislet cell tumors. Insulinomas are tumors that originate in the beta cells of the islets of Langerhans, which compose the APUD system, the meaning of which is: A=Amino, P=Precursor, U=Uptake, D=Decarboxylation. The cells fo the APUD system have common cytochemical characteristics with the ability to secret polypeptides and amines. Symptoms are related to the peptide secreted by the tumor, and some tumors can produce multiple peptides. Gastrinomas comprise about 60 % of type 1 MEN-associated islet cell tumors. Gastric acid hypersecretion results from excess gstrin secretion and causes multiple gastric and duodenal ulcers (Zollinger-Ellison syndrome). The author describe an experience with this pathology with special reference to diagnostic methods, treatment, follow-up, laboratory studies and localization of the tumor.
