Tienen la capacidad de secretar péptidos y aminas bioactivas. La Organización Mundial de la Salud (OMS) los clasifica de acuerdo con el grado de diferenciación y conducta biológica en 5 grados. Las manifestaciones clínicas pueden estar ausentes o ser inespecíficas. Se reporta el caso de un paciente de 49 años de edad quien fue ingresado por dolor abdominal en hemiabdomen derecho, acompañado de aerogastria, vómitos y síndrome constitucional; en el examen físico se encontró hepatomegalia dolorosa con nódulo único de 2,5 cm aproximadamente. La citología por aspiración con aguja fina (CAFF) y la laparoscopia con biopsia diagnosticaron una metástasis hepática única de un TNE de origen gastrointestinal, que se confirmó con la colonoscopia con ileoscopia encontrando un tumor subepitelial en la válvula ileocecal. La inmunohistoquímica realizada ayudó a la confirmación del diagnóstico. El tratamiento puede ser quirúrgico; sin embargo, este paciente rechazó esta terapia, por lo que se trató con quimioterapia y radioterapia. Lo fundamental en esta entidad es el diagnóstico precoz, que pocas veces se realiza por lo infrecuente de la enfermedad.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract Neuroendocrine tumors of the gastrointestinal tract are very rare tumors that most frequently occur in the small intestine, primarily in the ileum. They secrete bioactive peptides and amines. The World Health Organization (WHO) classifies them into five grades according to the degree of differentiation and biological behavior. Clinical manifestations may be absent or nonspecific. We report the case of a 49-year-old patient who was admitted due to abdominal pain in the right hemiabdomen, accompanied by aerogastria, vomiting and constitutional syndrome. A painful hepatomegaly with a single nodule of approximately 2.5 cm was found during physical examination. CAFF and laparoscopy with biopsy diagnosed a single hepatic metastasis of a neuroendocrine tumor of gastrointestinal origin. This was confirmed by colonoscopy with ileoscopy which found a subepithelial tumor in the ileocecal valve. Immunohistochemistry helped confirm the diagnosis. Treatment for this type of tumor can be surgical, but this patient rejected surgery. It was treated with chemotherapy and radiation therapy. Early diagnosis of this entity is fundamental but is rare because of the infrequency of the disease.]]></p></abstract>
