Cystitis cystica is a benign reactive urothelial lesion characterised by cystic dilatation of von Brunn nests within the lamina propria, usually secondary to chronic mucosal irritation. Although commonly encountered incidentally in adults, it is uncommon in children and may present with atypical clinical features, often mimicking neoplastic or vascular lesions. Hereby, the authors present a case report of an eight-year-old female child who was brought to Paediatric Outpatient Department (OPD) by her mother with perineal itching, bleeding and dysuria for the past two to three days. Clinical examination revealed an exophytic periurethral mass. Contrast -enhanced Computed Tomography (CECT) of abdomen demonstrated a well-defined lesion with increased vascularity, raising suspicion of a vascular malformation or neoplasm. Cystoscopy revealed no intravesical pathology and a biopsy was obtained from the periurethral mass. Histopathological examination showed cystically dilated von Brunn nests with prominent vascular channels, consistent with cystitis cystica, without evidence of dysplasia or malignancy. The postoperative course was uneventful. The present case highlights the diagnostic challenge posed by atypical presentations of cystitis cystica in children and underscores the importance of histopathological confirmation to avoid overtreatment. Early recognition and appropriate evaluation are essential in paediatric practice to ensure optimal management and follow-up.
