A case report of atypical granular cell tumor of bladder.

INTRODUCTION AND IMPORTANCE

The development of granular cell tumor (GCT) in urinary bladder is a very rare disorder.

CASE PRESENTATION

We reported a 50-year-old male, who was referred with vague pelvic pain. There was a hypoechoic mass with diameters of 30*25 mm in frontal wall of bladder in the sonogram.

CLINICAL DISCUSSION

The patient underwent transurethral resection of the bladder tumor. Subsequent pathology and immunohistochemistry findings supported the diagnosis of atypical GCT.

CONCLUSION

The patient was tumor-free at the follow up. It seems that GCT is usually benign in nature and can be treated by excisional surgery.
