  • Surgical management is en bloc resection of bladder, urachal remnant, and umbilicus. (wikipedia.org)
  • Concomitant cystitis glandularis occurs in the majority of cases, but is not considered a definitive precursor lesion since adenocarcinoma can develop in the absence of cystitis glandularis and only a small number of bladders with cystitis glandularis actually develop malignancies [ 2 ].

  • The potential for adenocarcinoma to develop in the defunctionalized bladder that is left in-situ at the time of urinary diversion is rare [ 3 - 5 ]. (biomedcentral.com)
  • The most frequent initial symptom is haematuria which occurs when the urachal tumour has penetrated the bladder wall, but mucinuria (mucin in the urine), local pain or swelling, recurrent local or urinary tract infections and umbilical discharge can (but is not always) be seen. (wikipedia.org)
  • These findings can be precursor lesions of a primary bladder adenocarcinoma. (wikipedia.org)
