Dumbbell-shaped swellings in neurofibroma have been commonly described in the spine, thorax, cranial cavity, and pelvis; however, dumbbell-shaped swellings in the peripheries are rare. Here, we report a dumbbell-shaped neurofibroma over the pinna in an 18-year-old female patient, its successful surgical management, and its association with Hashimoto thyroiditis.To the best of our knowledge, this is the first ever case to be reported of a dumbbell-shaped neurofibroma over the external ear and only the fourth case of neurofibromatosis type 1 (NF1) to be associated with Hashimoto thyroiditis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
