title: Nerve sheath myxoma of digital nerve.
abstract: A case of a dermal nerve sheath myxoma arising in a digital nerve is reported. Similar tumors and its variants have been termed neurothekeoma, pacinian neurofibroma, bizarre cutaneous neurofibroma, and plexiform neurofibroma. The perineural sheath or the Schwann cell have been presumed to be the cell of origin by several investigators. The positive reaction with antibody to S-100 would appear to favor the Schwann cell as the progenitor of this tumor.
