Traumatic neuroma is a well-defined clinicopathologic entity that is seldom associated with vascular neoformations. We describe the case of a patient with a postsurgical retroauricular neuroma that was associated with a coexisting arteriovenous aneurysm. We also performed an extensive immunohistologic characterization of the traumatic neuroma.
