Insights
This report details a rare inflammatory myofibroblastic tumor of the bladder in a 72-year-old man. Preoperative diagnosis was urachal tumor, confirmed as inflammatory myofibroblastic tumor post-surgery.
Area of Science:
- Urology
- Oncology
- Pathology
Background:
- Inflammatory myofibroblastic tumor (IMT) is a rare neoplastic proliferation.
- Bladder IMT is uncommon, with limited reported cases, particularly in Japan.
Observation:
- A 72-year-old male presented with symptoms suggestive of a urachal tumor.
- Diagnostic workup included urine cytology, cystoscopy, and magnetic resonance imaging.
- Surgical intervention involved a partial cystectomy.
Findings:
- Histopathological examination confirmed the resected bladder tumor as an inflammatory myofibroblastic tumor.
- This represents the 51st reported case of bladder IMT in Japan.
- The patient experienced no local recurrence during a 13-month follow-up period.
Implications:
- This case contributes to the understanding of rare bladder neoplasms.
- Highlights the importance of comprehensive diagnostic evaluation for urachal and bladder masses.
- Suggests favorable outcomes for surgically treated bladder IMT.
Abstract:
Here we report a rare case of inflammatory myofibroblastic tumor of the bladder. The patient was a 72-year-old man. We diagnosed this case preoperatively as urachal tumor from urine cytology, cystoscopy, and magnetic resonance imaging. We performed partial cystectomy. Histopathological examination revealed that the tumor was an inflammatory myofibroblastic tumor. To our knowledge, this is the 51st reported case of inflammatory myofibroblastic tumor of the bladder in Japan. He has been followed up for 13 months without any evidence of local recurrence.
