Introducción:

El uraco o conducto onfalomesentérico es una estructura embrionaria que conecta el intestino medio y el saco vitelino, que involuciona antes del tercer trimestre de embarazo.

Objetivo:

Presentar un caso con diagnóstico de adenocarcinoma uracal, neoplasia maligna rara.

Desarrollo:

Paciente de 50 años de edad sin antecedentes patológicos, con cuadro clínico inicial de ascitis y dolor abdominal, al examen físico masa palpable en hipocondrio-fosa iliaca izquierda que en la tomografía abdominal se observa una masa adyacente a la cúpula vesical y pared anterior del abdomen. El resultado de la biopsia reportó un adenocarcinoma mucinoso del conducto onfalomesentérico (uracal). Al momento del diagnóstico, el paciente se encontró en un estadio IVB según el sistema Sheldon y otros y un IV según sistema Mayo, etapa avanzada de la enfermedad que determina mal pronóstico. Se instauró tratamiento con quimioterapia neoadyuvante, quirúrgico y continuación con quimioterapia adyuvante, el cual continúa, actualmente, con una evolución estable.

Conclusiones:

Esta es una neoplasia rara. Sospechar su diagnóstico llevará a un diagnóstico temprano, lo que mejorará el pronóstico y sobrevida de los pacientes afectados.

Introduction:

The urachus or omphalomesenteric duct is an embryonic structure connecting the midgut and the yolk sac, which regresses before the third trimester of pregnancy.

Objective:

To report a case with a diagnosis of urachal adenocarcinoma, a rare malignant neoplasm.

Case report:

A 50-year-old patient with no pathological history, who had an initial clinical condition of ascites and abdominal pain. At physical examination, we found a palpable mass in the left hypochondrium - iliac fossa, which revealed a mass next to the bladder dome and anterior wall on the abdominal tomography of the abdomen. The biopsy result reported a mucinous adenocarcinoma of the omphalomesenteric duct (urachal). At the time of diagnosis, the patient was in stage IVB according to the Sheldon et al system and IV according to the Mayo system, an advanced stage of the disease that determines poor prognosis. Treatment with neoadjuvant and surgical chemotherapy was established and adjuvant chemotherapy to follow, which currently continues with a stable evolution.

Conclusions:

This is a rare neoplasm. Suspecting its diagnosis will lead to an early diagnosis, which will improve the prognosis and survival of affected patients.
