A Case of Retorauricular Neurothekeoma
|
|

Abstract
|
|
|
Neurothekeoma is rare cutaneous tumor that was first described by Gallager and Helwig5) in 1980. On histological findings, this tumor is most closely related to the neurofibroma. Although it is not certain whether their cells resemble the
perineural
cell or the classic Schwann cell, but the positive staining for S100 protein suggests that neurothekeoma is a tumor of Schwann cell origin.
We present a typical case of neurothekeoma arising on the retroauricular skin, an unusual site for this tumor, in a 19-year-od man.
