Low-grade papillary urothelial neoplasm: A case report study.

Urothelial carcinoma (UC) of the bladder is a prevalent malignant tumor among the elderly, whereas its incidence is scarce in the first 2 decades of life. The most commonly reported symptom in the literature is isolated hematuria, frequently overlooked during the initial medical assessment. In this study, we present the case of a 3-year-old male with hematuria, accompanied by other irritative symptoms such as flank pain, nausea, and vomiting.
