Diagnostic electron microscopy of head and neck tumors.

摘要: One hundred sixty-one neoplasms from the region of head and neck were studied by electron microscopy to define (1) subcellular structures important essential diagnosis, (2) application and/or limitations fresh, formaldehyde-fixed, paraffin-blocked tissues for diagnostic use. It was concluded that microscopical identification specific cytoplasmic helpful in diagnosis neoplasms, especially those equivocal at light level. Although could permit a more accurate classification many cases, it little value separating benign malignant lesions. also formaldehyde-fixed tissue reliable source material these studies. Paraffin-embedded much limited.
