A 66-year-old man with a history of sporadic von Recklinghausen' s disease was treated for pseudosarcomatous myofibroblastic proliferation in the bladder. The patient had a history of repetitive recurrence of bladder carcinoma requiring transurethral resection (TUR) 4 times and 1 course of intravesical BCG instillation. Three months after the fourth TUR, an intravesical solid mass 4 cm in diameter was detected. Suspicion of recurrent bladder carcinoma led to a fifth TUR procedure. Pathological findings showed submucosal growth of myofibroblasts with myxoidal stroma and we made a diagnosis of Pseudosarcomatous myofibroblastic proliferation. The patient was well with no evidence of recurrence after 1 year.
