A role for electron microscopy in salivary gland neoplasms.

Undoubtedly, electron microscopy has a specific role to play in the diagnosis of a select group of salivary gland neoplasms. However, this tool has a current central role, along with immunohistochemical techniques, in elucidating morphogenetic processes in salivary gland tumors. New information gained from ultrastructural surveys of these tumors can be applied to improving classification and the diagnostic problems that are not infrequent for the surgical pathologist with salivary gland lesions.
