HSV cytopathic effect (intranuclear Cowdry type A inclusions) is identified most reliably in viable squamous epithelium, thus, brushings or biopsy of the ulcer edge, rather than the ulcer base, will have the highest diagnostic yield (Figure 4) [12,14-16].

At ASVL, viral cytopathic effect was observed in viral culture cells from the specimen collected from the woman on October 10; however, immunofluorescent antibody staining was negative for herpes simplex virus (HSV).

We suspected a malignancy, but histopathology of biopsy specimens revealed that the mass exhibited the classic signs of the HSV cytopathic effect, including the presence of intranuclear inclusion bodies, ballooning degeneration of epithelial cells, and a ground-glass appearance of some nuclei.

At that time, the most rapid diagnosis was by production of cytopathic effect after subpassage in tissue culture (7), but most coronaviruses were recognized only with the use of human embryo tracheal organ cultures, and viral presence was detected by cessation of ciliary motion, by electron microscopy of nutrient media, or most cumbersome of all, by inoculation and production of colds in human volunteers (8, 9).

Similarly, is the cytopathic effect because of the prior chemoradiation therapy, which can cause damage by both direct cytotoxic effect and treatment-induced ischemia, or is the cytopathic effect related to typical tumor outgrowth of its vascular supply, resulting in ischemic injury?
