| description | Embryonal rhabdomyosarcoma (ERMS) of the adult urinary bladder is a rare malignant tumour. Inflammatory myofibroblastic tumour (IMT) of the bladder is a benign genitourinary tumour that may appear variable histologically but usually lacks unequivocal malignant traits. Techniques like flow cytometry and immunohistochemistry may be used to differentiate these two tumours. Our patient, a 46-year-old male, had rapidly recurring lower urinary tract symptoms after two transurethral resections of the prostate. He subsequently underwent a transvesical prostatectomy which showed IMT on histology. However, his symptoms did not resolve and an open resection done at our institution revealed a 6 cm tumour arising from the right bladder neck. This time, histology was ERMS with diffuse anaplasia of the bladder. Rapid recurrence of urinary symptoms with prostate regrowth after surgery is unusual. Differential diagnoses of uncommon bladder malignancies should be considered if there is an inconsistent clinical course as treatment approaches are different. |
