Two cases of Granular cell myoblastoma in the tongue

Granular cell tumor of the tongue A morphological report of a case with particular reference to histogenesis.

“…EVERSOLE et al [23] believed that the varied light and electron microscopic features of granular cell tumors could not possibly have substantiated a single specific progenitor cell in three cases and tney proposed tne term gran mai SIICUL11 iunkin iu' this tumor. Other investigators also believe that this lesion does not arise from a single cell type [21,22,24,25]. In our present case the relationship to nerve fibers and the existence of axon were not observed, but the tumor cells resembled Schwann cells in view of electron microscopic observations where the nuclei and cell membrane, …”

“…Most authors now believe that the tumor is not derived from a single cell type [21][22][23][24][25].…”
