Case report: sarcomatoid carcinoma arising from the ureter: a rare case and a treatment dilemma.

We report an interesting case of a patient with sarcomatoid carcinoma arising from the left ureter who presented with left iliac fossa pain. The diagnosis was based on CT and histological findings. To our knowledge, this is the first case of sarcomatoid carcinoma arising from the ureter reported. The literature review also highlights the rarity and the poor prognosis of the disease despite aggressive interventions.
