Giant vulvar verruciform xanthoma in a child: a rare case report and literature review.

Verruciform xanthoma (VX) is a rare benign mucocutaneous proliferative lesion that primarily affects the oral mucosa and, in rare cases, the genital mucosa and skin. Due to its uncommon occurrence and varied, non-specific clinical manifestations, the condition is prone to misdiagnosis and missed diagnosis. This report introduces an even rarer case of pediatric vulvar VX, providing a detailed interpretation and analysis of the ultrasonographic features of this condition. Furthermore, in conjunction with previous literature, this report summarizes and analyzes the currently reported vulvar VX cases, aiming to obtain effective diagnostic and therapeutic information, enhance preoperative diagnostic accuracy, and improve patient prognosis.
