Article Synopsis
  • The urachus is a leftover structure from fetal development that connects the bladder to the belly button, and cancers arising from it, known as primary urachal carcinoma, are rare but aggressive.
  • A case study presents a 48-year-old woman with abdominal pain and a mass, which was diagnosed as squamous cell carcinoma after imaging and biopsy.
  • Treatment typically involves surgery to remove the tumor and surrounding tissue to reduce the chance of spreading, but guidelines are sparse due to the rarity of this type of cancer, with current protocols based on limited data.
