Introduction. Inflammatory myofibroblastic tumor of the bladder or
inflammatory pseudotumor is benign in nature. It is also known as a
pseudotumor, because it macroscopically mimics infiltrative tumors of the
bladder. The first inflammatory pseudotumor ever described was found in the
lungs. In the 80s of the last century, it was first described in the urinary
bladder. Its etiology is unknown and the incidence is extremely rare. Case
Report. We present a case of a 46-year-old man who came to the Emergency
Center for the first time due to an unpleasant feeling when urinating,
painless hematuria and appearance of blood clots during urination. An urgent
diagnosis revealed a tumor mass in the bladder. Additional diagnostics and
surgical treatment was performed by transurethral electroresection of the
urinary bladder. After the histopathological examination, an inflammatory
myofibroblastic tumor of the bladder was diagnosed. The patient was
discharged on the third day of admission. On control examinations, the
patient underwent only cystoscopy and ultrasonography. No recurrences were
observed. Conclusion. A review of the available literature showed that in
such cases, after transurethral resection of bladder tumor, most urologists
opted for more radical surgical procedures. After a two-year follow-up, we
proved that a tumor of the bladder can be kept under control after
transurethral resection of bladder tumor, without recurrence, by regular
monitoring using ultrasonography and cystoscopy.
