The cytologic features of chlamydial cervicitis.
Chlamydial cervicitis is a common and important infection. Diagnostic cytologic criteria have been proposed, but not generally accepted. To better evaluate the cytologic changes, cervical cultures for Chlamydia trachomatis and duplicate cervical smears for Papanicolaou staining and immunofluorescence staining for chlamydial organisms were taken from 496 patients. A total of 61 (12.3%) of the patients had a positive culture for C. trachomatis. By immunofluorescence, the organisms were present as very small extracellular elementary bodies in mucus or as similar bodies in leukocytes; inclusions within epithelial cells were seen in only two cases. The organisms did not stain with the Papanicolaou stain. Chlamydial infection correlated with the degree of inflammation, with the presence of histiocytes and lymphocytes, especially large "transformed" lymphocytes, and with the presence of unidentified short bacteria, which stained red with the Papanicolaou stain. These features predict which patients should be tested more definitively for the presence of chlamydial organisms. However, we found no cytologic criteria that can reliably permit its diagnosis.
