Busulfan-induced hemorrhagic cystitis

We report a case of severe hemorrhagic cystitis induced by prolonged busulfan therapy. The clinical course and pathological results were similar to irradiation and cyclophosphamide cystitis. Only 1 such case has been described previously. Although hemorrhagic cystitis induced by busulfan is a rare complication it should be considered in the differential diagnosis and busulfan should be discontinued immediately.
