Giant arteriovenous malformation of the face and upper lip

A 35-year-old male patient reported with the chief complaint of a large swelling in the right side of the upper lip. The lesion measured 6.5 cm measuring from the infraorbital region to the lower border of mandible on the right side of the face and 7.5 cm from the right ear lobule to the contralateral commissure of the left side of the face. On palpation, the swelling was soft, fluctuant and compressible. Pulsations were felt, and on auscultation, bruit was also heard. Computed tomography angiogram of the neck and circle of Willis showed serpiginous hyperdense vascular channels causing significant soft-tissue thickening of the upper lip, right cheek region and philtrum. Hence, the diagnosis of diffuse subcutaneous facial arteriovenous malformation involving the right cheek and philtrum was given. The entire lesion was excised. In the postoperative 2^nd month, secondary cosmetic correction or lip reconstruction was done. The patient was reviewed after 3 years; there was no recurrence of the lesion.
