en تخصصي Special گزارش مورد case report Angiolipoma is an uncommon benign fatty tumor which is a variant of lipoma. Microscopic studies on angiolipoma show that it includes the mature lipocytes and blood vessels. Infiltrating angiolipoma is an un-capsulated angiolipoma and, due to penetration into the surrounding structures, complete excision of the tumor is difficult. According to previous studies, the relapse rate of the infiltrating angiolipoma after surgical intervention is 35-50%. Infiltrating angiolipoma is rarely seen in the head and neck region and often occurs in the trunk and limbs. In this study, we report a 10-year-old boy with periauricular infiltrating angiolipoma who underwent surgery. After surgery, the patient developed transient left frontal branch palsy, but recovery was excellent and after one year there is no relapse.
