Malignant inflammatory myofibroblastic tumor of the bladder with rapid progression.
A 71-year-old man was referred for painless hematuria and a bladder tumor. Cystoscopy and computed tomography revealed a 3-cm oval nodular mass on the left lateral side of the bladder. The patient underwent a complete transurethral resection of the lesion and histology showed a proliferation of atypical spindle cells with inflammation consistent with a myofibroblastic tumor. After 4 and 7 months, follow-up cystoscopy demonstrated nodular mass lesions and transurethral resection of bladder tumor was done, which showed chronic cystitis and a recurred myofibroblastic tumor, respectively. Five months later, multiple lymph node, bone, and soft tissue metastases were found by positron emission tomography. The patient was treated first with palliative chemotherapy, including doxorubicin and cisplatin. After that, radiologic studies showed disease progression but the patient refused further treatment and died 6 months later.
