The sarcomatoid carcinoma of the urinary bladder is a rare variant of transitional carcinomas with an extremely aggressive clinical course and dismal prognosis regardless therapies. The diagnosis of a bladder sarcomatoid carcinoma involving perivesical tissues with limphnodal, hepatic and lung metastasis was done in a 34-years old male. The disease underwent complete remission after neoadjuvant chemotherapy with adriblastine and ifosfamide, radical surgery and adjuvant chemotherapy with the same drugs, as confirmed by CT, vesical biopsies during chemotherapy and by the findings detected on the surgical specimen. Follow-up is negative for relapses at 72 months. The sarcomatoid bladder carcinoma is a rare variant of transitional carcinoma (0.31%), usually diagnosed in the late decades of life, with a survival time of a few months for metastatic patients regardless of any adopted therapies. The case presented is remarkable due to the young age of the patient but, overall, for the complete and durable regression of the disease achieved applying a chemotherapic scheme commonly adopted to treat pure sarcomatous mesenchimal neoplasms. Due to the rarity of the disease and the consequent unfeasibility of randomized studies, in our opinion these results, even if obtained in a single case, suggest a viable therapeutic option.
