In this study, we present a representative case of multiple glomuvenous malformation in a 12-year-old female patient. Approximately five years ago, the patient developed multiple blue-purple papules and plaques on her hypogastrium and right thigh, which progressively enlarged and presented tenderness. Histopathological examination confirmed the diagnosis of glomuvenous malformation. Following two injections of lauromacrogol, a significant improvement was observed in the lesions, including a resolution of tenderness. These findings suggest that sclerotherapy not only exhibits evident therapeutic efficacy but also effectively alleviates pain while addressing both aesthetic and therapeutic concerns.
