[Rhabdomyosarcoma of the bladder in a 2-year-old boy].
A case of rarely occurring rhabdomyosarcoma of the urinary bladder in a boy of 2 is presented. The period from the first clinical manifestations (pyuria, macrohematuria) to death was 4 months. Urological examinations were done at the period of manifest clinical signs of disuria. A tumour of the urinary bladder almost completely filling the lumen was found in the form of numerous papillary-polyplike formations, with uropassage disorders. On the materials of operation biopsy the histological conclusion of urinary bladder rhabdomyosarcoma was reached. The death occurred with urogenic infection and manifestations of drug agranulocytosis (cytostatic therapy). The tumour outgrew into the posterior wall, no metastases were found. Histologically the tumour was characterized by random arrangement of mono- and multinuclear polymorphic cells with oxiphilic cytoplasm. The granularity and fibrous pattern of the cytoplasm were discernible. Typically, an argirophilic framework was observed. By its histological structure the tumour belongs to the embryonal type.
