Robot-assisted Partial Cystectomy for Treatment of Inflammatory Myofibroblastic Tumor of the Bladder

Abstract

Inflammatory myofibroblastic tumors rarely occur in the urinary bladder. These masses follow an indolent course, but due to their histologic similarities to more malignant types of bladder masses, they must be differentiated with immunohistochemical staining. Once diagnosed, the mainstay of treatment for these masses is surgical resection. Due to advancements in robotic surgery, new surgical techniques can be employed to treat these masses with fewer perioperative complications. We report a case of inflammatory myofibroblastic tumor of the urinary bladder in a 29-year-old male treated with robot-assisted partial cystectomy.

Inflammatory myofibroblastic bladder tumor with divergent behavior in a patient with spinal cord injury

“…These lesions develop in various organs, such as the lung, retroperitoneum, and pelvis . IMT of the bladder represents less than 1% of all bladder tumors and is therefore one of the most difficult diagnostic dilemmas in genitourinary pathology …”

Minimally invasive surgery for inflammatory myofibroblastic tumor of the urinary bladder

“…IMTUB is a rare tumor of indeterminate malignant potential and comprises less than 1% of all bladder tumors. [2] The common manifestations of IMTUB include anemia and gross hematuria, accompanied by pain sometimes during urination. Teoh et al [6] reported that high possibility of IMTUB should be suspected for young patients presenting with gross hematuria and severe anemia.…”

“…Laparoscopic approach is safe in selected patients and may yield satisfactory oncological and functional results. [13] Recently, Rotenberry et al [2] reported a patient of IMTUB who was treated by robotic-assisted laparoscopic partial cystectomy with good prognosis. Compared with open partial cystectomy, laparoscopic or robot-assisted laparoscopic approach has several advantages, including cosmetic factors, lower risk of postoperative complications and shorter postoperative hospital stay.…”

“…Inflammatory myofibroblastic tumor (IMT) is proliferative lesions arising from submucosal stroma, of low or indeterminate malignant potential with the bladder being the most common site involved in the genitourinary tract. [1] However, IMT of the urinary bladder (IMTUB) is rare and comprises less than 1% of all bladder tumors, [2] which was firstly introduced by Roth in 1980. [3] The average age of presentation is 28 years with hematuria and severe anemia being the most common manifestations.…”
