Case ReportA 25-year-old male came to our observation with a congenital vascular malformation in the dorsal region of the glans ( Figure 1A). The patient did not complain of erectile dysfunction, bleeding, hemospermia, or macrohematuria; however, the lesion was unaesthetic and a source of psychological problems for the patient. On examination, the malformation proved to be localized, situated prevalently at the apex of the glans, and included the balanopreputial groove and the base of the glans. The surface was very irregular and red. The varicosity decreased considerably in size on slight digital compression. No similar lesions were identified on the rest of the body. A dynamic penile echo-color Doppler scan showed clear separation between the cavernous body and the vascular formation. A biopsy of the lesion was obtained before sclerotherapy. Histologic examination confirmed the diagnosis of venous vascular malformation.Sclerotherapy was performed in three stages. Polydocanol (hydroxy-polyethoxy-dodecane with 5% pure ethanol) was used as the sclerosing agent. After local anesthesia with 5% lidocaineprilocaine cream for 20 minutes and creation of a venous line with an 18-gauge needle-cannula for infusion of hydrating and alkalinizing solutions as well as antibiotic prophylaxis (single dose of 1 g cefotaxime), the glans was suitably disinfected with povidoneiodine (0.1% active iodine) solution. A tourniquet was placed around the penile shaft, proximal to the lesion. The tourniquet remained in position during injection and for 5 minutes afterward, to contain the sclerosing agent within the venous malformation. A 25-gauge needle connected to a syringe containing 2% polydocanol was inserted into the venous space, and the intraluminal position of its tip was confirmed by blood aspiration. The sclerosant was then injected slowly into the lesion. The volume of solution was 1 mL at the first application and 2 mL at the second and third applications. After treatment, intravenous hydration with 1 L Ringer lactate solution, shortterm low-dose corticosteroids (0.05 mg/kg dexamethasone), and antibiotic prophylaxis (single dose
