Pleomorphic Rhabdomyosarcoma Of The Urinary Bladder ?mitating A Pelvic Mass: A Case Report

Aims: Rhabdomyosarcoma of the urinary bladder is exceedingly rare in adults. The most common type is pleomorphic rhabdomyosarcoma. So far, more than a hundred of case reports were published in the literature about adult urinary rhabdomyosarcoma, but our case is the 23th pleomorphic type adult rhabdomyosarcoma in the literature. So, we wanted to share this case report with other clinicians. Presentation of Case: In this case report, we presented a patient who admitted to urology outpatient clinic with abdominal pain, painless hematuria and lower abdominal intumescence. First, imaging techniques showed a pelvic mass. Further investigations revealed bladder rhabdomyosarcoma. The mass had originated from the right side of the bladder and was partial excised with a pelvic operation by extraperitoneal. Our case died 11 months later after the initial diagnosis and radiotherapy and chemotherapy following partial cystectomy. Discussion: Rhabdomyosarcomas are rarely seen tumors in adults. Metastasis of the primary tumor usually to the regional lymph nodes, lungs and liver. Presenting symptoms are hematuria, dysuria, and more frequently, bladder dysfunction in clinical pactice. Because of the rarity of adult rhabdomyosarcoma of the bladder, optimal therapy is not clear. Conclusion: Bladder involvement of Rhabdomyosarcomas has been reported very rare in the literature. Local recurrence is seen frequently as well as distant metastases. The survival is very short because of the aggressive behaviour of the tumor. Rhabdomyosarcoma has a rapid progression and poor prognosis.
