[On neurogenic granular cells and their relationships to the so-called granular cell myoblastoma (author's transl)].
A report on granular cells found in biopsy material is presented. Morphologically identical patterns were seen in a pigmentated granular 'rankenneuroma' and in a patient with a morphea of the tongue. The independent development of granular cells in tumorous and nontumorous tissue supports the idea that the so-called granular cell myoblastoma originates from degenerative alterations of Schwann cells.
