Caso de rabdomiosarcoma vesical en niña de 6 meses

Abstract

Rhabdomyosarcoma is the most common soft tissue sarcoma in childhood, more frequently affecting males, with an incidence of 8 children per one million. It is found in the genitourinary tract in 26% of cases. Differential diagnoses are ureteral polyps and ureterocele. The most frequent subtype in children is embryonal rhabdomyosarcoma and the botryoid variant with a polypoid form arises from the cavitied structures.

The characteristics of a case of botryoid rhabdomyosarcoma in the bladder cavity of a 6-month-old infant girl and the importance of its differential diagnoses are described.

We present herein a rare case of bladder tumor in the bladder cavity for a better understanding and recognition of this type of disease in pediatric urology.
