Adenocarcinoma de uraco. Reporte de caso

Description: we present a 58-year-old man who came to the emergency room complaining of macroscopic hematuria. As a result of the diagnostic protocol, an extra-bladder tumor. A wide en bloc resection of the umbilical scar, middle umbilical ligament and bladder dome was performed. Diagnosis of poorly differentiated carcinoma of the peribladder soft tissues (urachus), T3 according to Sheldon's classification, surgical margins free of lesion, angiolymphatic invasion present. At 48-month follow-up, the patient remains negative for recurrence or metastasis. Relevance: it is important to know the topic and make a differential diagnosis in patients who present with hematuria, as well as collaborate to compile evidence from similar clinical cases, in this way obtain greater knowledge of risk factors, with the subsequent preparation of detection protocols. Clinical implications: urachal tumors constitute less than 1 % of bladder neoplasms, being a pathology of limited knowledge. A clinical case of urachal adenocarcinoma is presented, to provide evidence to the literature. Conclusions: the diagnosis of urachal adenocarcinoma is rarely considered in a patient with hematuria, and although its prevalence is low, it is important to promptly identify the disease to avoid complications and morbidity and mortality in our patients.
