Low-grade papillary urothelial neoplasm: A case report study

Abstract

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. Ultrasonography revealed a bladder mass, which was later confirmed to be a noninvasive low-grade papillary urothelial carcinoma (NLPUC) through histopathological examination. This report discusses the clinical and pathological characteristics of the case and examines current literature on the topic.
