Abstract

Transmission electron microscopy (TEM) is an important adjuvant to light microscopy, but is underutilized in cytopathology because of technical obstacles. One should attempt to obtain properly fixed material for TEM whenever possible. If that is not available, TEM on the cell block requires no preplanning or additional needle passes, and avoids problems of inadequate tissue for diagnosis. However, cell blocks are often not examined because of the perception that their poor ultrastructural preservation precludes their utility. We describe our experience in performing TEM on cell blocks from 15 cytologic specimens. In 13 of15 cases, the cell block material was adequate for ultrastructural evaluation, and it clarified or extended the diagnosis in seven of thesecases. TEM is a useful adjuvant technique to cytodiagnosis and can besuccessfully performed on cell blocks when gluteraldehyde-fixed material is not available.
