title: Incidental Diagnosis of Giant Cell Tumor After Urachal Remnant Removal in a Thalassemic Child.
abstract: Urachal anomalies are relatively uncommon; they usually present in childhood as urachal cysts, urachal sinuses, diverticula, and patent urachus. The malignant involvement of the urachus, although rare in children, is commonly found in adulthood when adenocarcinoma accounts for the majority of the cases, representing up to 20-30% of all adenocarcinomas of the bladder. Urachal tumors of variable histology have been reported in children and adolescents as single case report. We present the first case of a 4-year-old thalassemic boy, with an incidental finding of giant cell tumor arising in an urachal remnant.
