Papanicolaou-stained cervicovaginal smears from six patients with herpes simplex virus (HSV) infection were destained and reprocessed by means of in situ hybridization (ISH) technique to demonstrate the presence of HSV DNA utilizing biotinylated probe. Positive results were obtained in all six cases with intense staining signal for the HSV DNA in the nuclei of cells having a ground-glass nuclear appearance as well as in multinucleated giant cells. Furthermore, a hybridization signal was also noted in smears that had been prepared as much as 3 yr previously. HSV type 2-specific antigen was confirmed in six destained smears by means of immunoperoxidase staining. Moreover, polymerase chain reaction (PCR) was also performed for four patients from Pap-destained cervicovaginal smears. Amplified HSV DNA was detected in all four cases as 106 basepair PCR products by polyacrylamide gel electrophoresis. The combined use of cytology and the ISH technique and PCR amplification was of great value for the rapid cytodiagnosis of genital infection of HSV.
