Bladder Neoplasia in Pediatric Patients—A Single-Center Experience Including a Case Series
Children
Objective: Bladder lesions like urothelial carcinoma are rare in the first two decades of life. A biopsy of the bladder or urinary cytological examination is seldom required. Gross painless hematuria is the most relevant clinical syndrome. Methods: A retrospective analysis of surgical pathology records collected between 1984 and 2014 at our institution was performed in a search for cases of urothelial neoplasms originating within the urinary bladder in pediatric patients. Diagnoses were confirmed based on pathologic examination using the 2004 World Health Organization (WHO) classification system. We selected keywords such as bladder neoplasia, bladder lesion, urothelial neoplasia, rhabdomyosarcoma, and children. In addition, we describe clinical presentation and diagnostic procedures as well as treatment and follow-up of two patients. A review of the literature was performed to analyze recommendations concerning diagnostic staging, treatment, and follow-up examinations as well as su...
Urothelial neoplasm of the bladder in childhood and adolescence: a rare disease
International braz j urol, 2016
Bladder tumors are rare in children and adolescents. For this reason, the diagnosis is sometimes delayed in pediatric patients. We aimed to describe the diagnosis, treatment, and follow-up methods of bladder urothelial neoplasms in children and adolescents. Materials and Methods: We carried out a retrospective multicenter study involving patients who were treated between 2008 and 2014. Eleven patients aged younger than 18 years were enrolled in the study. In all the patients, a bladder tumor was diagnosed using ultrasonography and was treated through transurethral resection of the bladder (TURBT). Results: Nine of the 11 patients (82%) were admitted with gross hematuria. The average delay in diagnosis was 3 months (range, 0-16 months) until the ultrasonographic diagnosis was performed from the first episodes of macroscopic hematuria. A single exophytic tumor (1-4cm) was present in each patient. The pathology of all patients was reported as superficial urothelial neoplasm: two with papilloma, one with papillary urothelial neoplasm of low malignant potential (PUNLMP), four with low grade pTa, and four with low grade pT1. No recurrence was observed during regular cystoscopic and ultrasonographic follow-up. Conclusions: Regardless of the presence of hematuria, bladder tumors in children are usually not considered because urothelial carcinoma in this population is extremely rare, which causes a delay in diagnosis. Fortunately, the disease has a good prognosis and recurrences are infrequent. Cystoscopy may be unnecessary in the follow-up of children with bladder tumors. We believe that ultrasonography is sufficient in follow-up.
Bladder urothelial neoplasms in pediatric age: Experience at three tertiary centers
Journal of pediatric urology, 2015
Urothelial bladder neoplasms (UBN) typically occur in patients in their sixth or seventh decade of life while they are infrequent in children and young adults. They occur in 0.1-0.4% of the population in the first two decades of life. Their management is controversial and paediatric guidelines are currently unavailable. To further expound the available data on the outcome of patients younger than 18 year old diagnosed with UBN. We retrospectively reviewed the files of all the consecutive paediatric patients with UBN treated in three tertiary paediatric urology units from January 1999 to July 2013. Lesions were classified according to the 2004 WHO/ISUP criteria as urothelial papillomas (UP), papillary urothelial neoplasm of low malignant potential (PUNLMP), low-grade urothelial carcinoma (LGUC), and high-grade urothelial carcinoma (HGUC). The table shows the results. Management after TURB varied among centres. One centre recommended only follow-up US at increasing intervals whereas a...
Urothelial Papilloma of the Urinary Bladder in Children: Report of Two Cases
European Journal of Pediatric Surgery Reports
Urothelial neoplasms of the bladder (UNB) are considerably rare throughout the pediatric population. UNB develops from the urothelial tissue in the form of a benign disease, generally favoring a successful prognosis in the majority of cases. The authors present the diagnosis and treatment regarding two medical case reports in which urothelial papilloma was diagnosed and effectively treated. Case 1: A 15-year-old male patient was presented to our clinic complaining of a painless yet distinctive, macroscopic form of hematuria. Following a routine examination, which included ultrasound (US) and intravenous pyelography, the urethrocystoscopy revealed an intravesical solitary lesion positioned in the vicinity of the left ureteral orifice. Additionally, histology confirmed urothelial papilloma. During the follow-up, laboratory, urinary control tests, and US results all proved negative. Case 2: A 13-year-old male patient was admitted to our clinic and examined, in regard to complaints asso...
Bladder Urothelial Carcinoma in a Child: Case Report and Review of Literature
Frontiers in Pediatrics, 2019
Bladder urothelial carcinoma (UC) it is the fifth most prevalent carcinoma in humans, nevertheless in children and young adults it's very rare. It usually occurs in older adults. Literature on UC in pediatric population is limited and important information (risk factors, follow-up protocols, etc.) are poorly defined. We present an 11-year-old boy with a painful macroscopic hematuria. Ultrasound revealed a heterogeneous intravesical mass without extravesical extension, which was confirmed by computed tomography (CT) and magnetic resonance imaging (MRI). The first biopsy was compatible with urothelial papilloma. After 1 year, he returned with a bigger mass. Transurethral resection of the bladder (TURB) was performed and immunohistochemistry showed low-grade papillary UC with a high-grade component, with tumor free margin. Tumor had mutations in the BRAF and KRAS genes. Two and a half years after the resection the patient has no recurrence. Less than 1% of bladder UC occur in the first two decades of life. Gross hematuria is a common symptom. Ultrasound is generally the first diagnostic tool. MRI is also helpful, but cystoscopy allows definitive diagnosis. Transurethral resection of the bladder (TURB) is the standard treatment, with good results and low recurrence rate, and it was the treatment of choice for our patient, that remains free of disease. The BRAF and KRAS gene mutations were never described before in pediatric UC. There are only few cases in literature of pediatric UC that present a tumor genetic profile; therefore, our case report adds more information to this very rare disease in children.
Urothelial Carcinoma in Pediatric Patient
Indian Journal of Surgery, 2015
Transitional cell carcinoma as a cause of hematuria is a rare entity in the pediatric age group. An 11-year-old child presented with gross, painless hematuria. Ultrasonogram and computed tomography scan of the child revealed a tumor in the posterolateral wall of the bladder. Cystoscopically, the mass was present in the bladder away from the trigone area about 2 cm lateral to the right ureteric orifice. Transurethrally, the tumor was excised by a cystoscope. Histopathologically, it was a low-grade noninvasive urothelial carcinoma of the bladder. A follow-up cystoscopy at 6 months and 1 year had no recurrence. Literature review revealed the pediatric age group as an uncommon age for urothelial carcinoma of bladder, which has a different biological behavior of being low malignant potential compared to their adult counterpart. They have been treated with transurethral resection of bladder tumor without any adjuvant therapy. There is no definite follow-up schedule for these tumors as it occurs in very small number of cases.

Background. Bladder cancer occurs mainly in adults. In children, younger than 10 years in particular, it is very rare. Objectives. The aim of the study is to retrospectively evaluate the efficacy of transurethral resection of the bladder tumour (TUR-BT) of transitional cell carcinoma (TCC) of the bladder in children. Material and Methods. Transurethral resection of the bladder tumour was performed in 7 boys aged 4 to 17 years (median 12.1 years). In all cases laboratory tests, ultrasound, and cystoscopic tumour biopsy were carried out prior to the resection. Doxorubicin was additionally instilled intravesically as one dose in two patients. The Foley catheter was left in the bladder for 1 to 4 days (median 1.85 days). The follow-up period ranged from 10 months to 10 years (median 4 years). Results. Papillary urothelial neoplasm of low malignant potential (PUNLMP) was diagnosed in 5 patients and urothelial papilloma in 2. Local recurrence was observed in one case two years after the resection. In all other cases complete remission was achieved. Conclusions. Transitional cell carcinoma of the bladder in children is usually benign and endoscopic treatment (TUR-BT) seems to be the treatment of choice. To determine a follow-up schedule a more substantial group of children with bladder cancer should be analysed (Adv Clin Exp Med 2015, 24, 3, 505-509).
