Granular cell tumor of the tongue: an electron microscopical and immunohistochemical study.
Granular cell tumor of the tongue in a 29-year-old woman is reported including details of studies using electron microscopy and immunohistochemistry. Immunohistochemically, the tumor cells showed moderate positivity for S-100 protein. Electron microscopically, basal lamina, angulate bodies, myelin-like figures and axon-like structures were observed in the tumor. These findings may indicate that this tumor is a lesion of Schwann cell origin. The Japanese literature on oral granular cell tumor is also reviewed and discussed.
