Treatment of metastatic urachal adenocarcinoma in a young woman: a case report.

A 30-year-old woman with a history of smoking presented with abdominal pain and haematuria. On physical examination, she had a palpable pelvic mass. Imaging revealed a large pelvic mass located on the dome of the bladder, extending from the urachus, with pulmonary metastases. After open biopsy, urachal adenocarcinoma was histologically confirmed. The patient received six cycles of palliative chemotherapy combination 5 fluorouracil and irinotecan with complete response on the pelvic mass and partial response estimated to more than 80% on pulmonary metastasis.
