title: Papillary adenocarcinoma of the urachus presenting as an umbilical mass.
abstract: A 53-year-old Caucasian female presented with an erythematous, tender, fluctuant mass in the periumbilical region. A computerized tomography scan of the abdomen and pelvis suggested a large tumor extending from the umbilicus to the dome of the bladder with elements of tissue within the bladder consistent with a malignancy of either bladder or urachal origin. The patient subsequently underwent a cystoscopic biopsy which was positive for papillary adenocarcinoma arising in a villous adenoma. Metastatic workup revealed multiple hepatic and bilateral pulmonarynodules. Palliative laparotomywithlysis of adhesions, smallbowel resection, partial cystectomy, omentectomy, abdominal wall and umbilical resection were performed.
