Abstract:
Myxoid neurofibroma (MN) is a benign tumor of perineural cell origin, which is demonstrated with a positive immunohistochemical staining for S-100 protein. The most common locations of the MN are the face, shoulders, arms, periungual and in the feet. To our knowledge, this is the first time that a trunk location is reported. MN should be included in the differential diagnosis of tumors on this location.
