RESUMEN

Objetivo: realizar una revisión bibliográfica y presentación de caso de colangiocarcinoma tubulopapilar. Material y Método: Se revisó la ficha médica y las características clínicas, radiológicas y patológicas del tumor, y la literatura científica respecto al carcinoma tubulopapilar. Caso Clínico: Paciente con ictericia progresiva asociado a baja de peso. El estudio imagenológico muestra amputación del tercio distal del colédoco por tejido de partes blandas, sugerente de colangiocarcinoma. Se realiza endosonografía, arrojando "fragmentos superficiales de adenocarcinoma tubulopapilar". Se realiza duodenopancreatectomía cefálica y, posteriormente, se inicia quimioterapia. Discusión: El colangiocarcinoma es una neoplasia de la vía biliar. Existen diferentes variantes histológicas, entre ellas el colangiocarcinoma tubulopapilar. Su diagnóstico se basa en estudios imagenológicos y anatomopatológicos. El principal hallazgo imagenológico va a depender del patrón de crecimiento tumoral; masiforme, periductal o intraductal. Dentro de los intraductales, se describe un carcinoma biliar con crecimiento tubulopapilar, con fenotipo pancreatobiliar epitelial. En los últimos años han sido de interés por tener mejor pronóstico. Conclusión: El colangiocarcinoma tubulopapilar es una variante histológica poco frecuente del colangiocarcinoma, que se asocia a un mejor pronóstico que otras variantes.

Objective: To conduct a literature review and present a case study of tubulopapillary cholangiocarcinoma. Material and Method: The clinical record and the clinical, radiological, and pathological characteristics of the tumor were reviewed, along with the scientific literature regarding tubulopapillary carcinoma. Case Report: Patient with progressive jaundice associated with weight loss. Imaging studies show amputation of the distal third of the common bile duct by soft tissue, suggestive of cholangiocarcinoma. Endosonography was performed, yielding "superficial fragments of tubulopapillary adenocarcinoma." Subsequently, a cephalic duodenopancreatectomy is performed, followed by chemotherapy. Discussion: Cholangiocarcinoma is a neoplasm of the biliary tract. There are different histological variants, including tubulopapillary cholangiocarcinoma. Its diagnosis is based on imaging and pathological studies. The main imaging finding will depend on the pattern of tumor growth: mass-forming, periductal, or intraductal. Among the intraductal types, a biliary carcinoma with tubulopapillary growth and an epithelial pancreatobiliary phenotype has been described. In recent years, they have been of interest due to their better prognosis. Conclusion: Tubulopapillary cholangiocarcinoma is a rare histological variant of cholangiocarcinoma that is associated with a better prognosis than other variants.
