摘要

Dear Editor, The urachus,which is a vestigial structure between the dome of the bladder and umbilicus,usually,retracts from the bladder before birth.However,the urachal remnant was continuous with the bladder cavity even in adults in 32％ of bladder in one autopsy study.1For this reason,tumors may develop from the remnants,most of which are well-differentiated mucinous adenocarcinomas,which is a rare form ofvesical malignancy,accounting for ＜ 1％ of all bladder cancers.Although local spread to the peritoneum is common at presentation,distant metastases without local recurrence are rarely detected following surgical excision of clinically localized disease.
