Tactile corpuscle-like structures in a case of plexiform neurofibromatosis

Tactile corpuscle-like structures were identified in a plexiform neurofibroma, which was localized on the right cranial hemisphere os a 16-year-old boy and had necessitated repeated surgery. These structures were studied by light and electron microscopy. The origin of their component cells is, however, still controversial. We believe to have accumulated sufficient evidence for a Schwann cell origin of these cells.
