A 17-year-old male presented to an emergency room with a genital lesion. A swab taken from the lesion produced herpes-like cytopathic effect in primary human amnion cells. However, attempts to pass the virus or confirm the presence of herpes antigens by direct fluorescent-antibody techniques were unsuccessful. Electron photomicrographs of the original specimen subsequently revealed the presence of poxviruses.
