Urinary Bladder Tumours in Children

Abstract

A short review is given of tumours of the urinary bladder in children, and the first case of an inverted papilloma in a child is reported. The tumour was situated in the trigone of the bladder and was successfully extirpated, with no recurrence at follow-up 9 months later. It was histologically typical of these tumours. The 105 patients described in the literature had an average age of 55 years, whereas the present case is the first to be described arising during the first two decades of life. The most frequent symptoms of such tumours are haematuria and urinary obstruction. It is suggested that the treatment of choice is transurethral excision. The term Brunnian adenoma is recommended for use with this tumour, in order to avoid the impression given by the name papilloma of the bladder, that the tumour is malignant.

Inverted Papilloma Arising in a Juvenile

“…The majority of patients with urothelial IP are between the sixth and seventh decades of life [5] and predominantly male. The previous reports in juve- nile patients were found in the bladder of 9-, 11-and 14-year-old boys [2][3][4]. The present case was also found in the bladder of a 15-year-old boy.…”

“…However, there have been only 3 cases in the first two decades of life [2][3][4]. The majority of patients with urothelial IP are between the sixth and seventh decades of life [5] and predominantly male.…”

Transitional cell papilloma of the bladder

“…Gross hematuria may be painless, intermittent and occasionally occurring at the end of voiding. Excretory urograms and cystograms have sometimes shown a defect in the partially filled urinary bladder, usually on the lateral wall [4]. In this case, an excretory urogram showed superimposition of bowel gas on the bladder and may have hidden the defect.…”

“…Atypia or frequent mitotic figures are unusual [4]. Invasion of the lamina propria or muscularis is not present.…”

Transitional cell papillary carcinoma of the bladder in a child

“…There is a male predominance (3 to 1). As opposed to the adult type, the tumor is usually of low grade (I or 2) and is not infiltrative; the evolution is benign and recurrences are exceptional [3][4][5][6]. As in adults, the first symptom is painless gross hematuria but in infants, this is more easily related to infections rather than to tumors.…”
