On radiological investigation he was  found to  have  a  tumor involving  dome of bladder and urachal remnant. Cystoscoic  biopsy  suggested carcinoma. Partial cystectomy  with enblock removal of urachus  and  umblicus  was done. On cutting  the  specimen through umblicus the  urachal remnant was  identified very well  with a tumor from distal urachus  infiltrating  into the  bladder. Histologicaly  this tumor  was  identified  as  adenocarcinoma-enteric  type  involving, urachus , bladder  and perivesical fat.
