title: Intraneural neurothekeoma: case report.
abstract: Neurothekeomas are rare, benign cutaneous tumors, with a distinctive histological appearance, that seldom have been documented to arise from identifiable medium- or large-caliber peripheral nerves. We report a neurothekeoma of the left posterior tibial nerve, whose gross histological appearance and strong immunostaining for S-100 in the majority of the tumor corroborates the impression that this tumor is a variant of a schwannoma.
