“…MRI findings were indicative of an infiltrating mass which involved the muscular layer of the bladder and the anterior uterine wall. Cystoscopy is essential in cases where bladder involvement is suspected, in order to obtain a biopsy prior to surgery 8. Cystoscopy in our case showed a broad-based, papillary growth arising from the bladder dome.…”

Laparoscopic excision of an inflammatory myofibroblastic tumour of the bladder disguised as deep infiltrating endometriosis

Inflammatory myofibroblastic tumour (IMT) of the bladder is a rare tumour of indeterminate malignant potential with myofibroblastic differentiation, with a generally benign but rarely aggressive behaviour. Vesical IMT is usually treated by transurethral resection or partial cystectomy. Herein we describe a case of a woman who underwent laparoscopic excision of an IMT of the bladder, initially diagnosed as deep infiltrating endometriosis.

“…It is usually difficult to differentiate between IMT of renal pelvis and other malignant tumors or conditions, such as blood clots of renal pelvis. The detection of ALK protein or rearrangements of the ALK gene has been previously considered a significant feature in the differential diagnosis of IMTs, but ALK + IMTs tend to occur more frequently in young patients, and their detection rate is low (~65% of all IMTs) (10). In the present case, contrast-enhanced CT scan revealed the presence of a slightly enhanced tumor of 1.5x1.0-cm in size in the left renal pelvis, which mimicked renal pelvic carcinoma.…”

Abstract. Inflammatory myofibroblastic tumor (IMT) is a rare type of mesenchymal tumor, which may affect various organs. The preferential site for IMT in the genitourinary system is the urinary bladder, while the presence of IMT in the kidney, and particularly in the renal pelvis, is rare. In the present report, the case of a 43-year-old man who was admitted to the Department of Urology of The Second Xiangya Hospital of Central South University (Changsha, China) in July 2012, with complaints of iterative gross hematuria and abdominal pain unresponsive to antibiotics is described. Computed tomography and magnetic resonance imaging indicated a slightly enhanced mass in the left renal pelvis of 1.5 cm in diameter. On request of the patient, a left nephrectomy was then performed, based on a suspected diagnosis of renal pelvic carcinoma. However, analysis of the intraoperative fast-frozen section exhibited proliferation of compact spindle cells, suggesting IMT. Therefore, further ureterectomy was avoided, and the patient remained in healthy condition thereafter.

“…Most of the patients are young, with a mean age of 38.9 years and a slightly female predominance of 51.7% in some studies [3], while others report a male predominance of 9 : 8 [4]. The most common symptom is hematuria, followed by irritative or obstructive voiding symptoms and lower abdominal pain [2, 3, 5].…”

Two cases of inflammatory myofibroblastic tumor (IMT) of the bladder are reported here. Both patients were male and presented with macroscopic hematuria; in the first case terminal hematuria was associated with irritative voiding symptoms. The second case was a smoker with hematuria unresponsive to medical treatment and anemia. Clinical presentation, pathological features, treatment, and prognosis are discussed. Due to rarity of this pathological condition, there are no guidelines concerning treatment and follow-up. We present our follow-up scheme and highlight the use of laparoscopic partial cystectomy as a successful treatment approach.
