[Histology of a plexiform neuroma with Vater-Pacini-lamellar-corpuscle-like structures].

From the finger of a 11 year old boy a tumor that had been present since birth was removed. Histological examination showed a great number of immature nerve bundles, and structures resembling Pacinian corpuscles. It could be shown that the organoid structures are a result of a proliferation of the so-called perineurial cells. These formations do not correspond with real tactile corpuscles, rather they can be considered as neoplastic structures of the perineurium.
