Cutaneous infections caused by Herpesviridae: a review.

Abstract

The herpes family of viruses accounts for a significant proportion of human cutaneous disease. Although most episodes of viral infection can be diagnosed clinically, a small subset of these outbreaks will require biopsy for histologic interpretation and diagnosis. Most herpesviruses cause characteristic architectural and cytologic changes in the context of active infection, whereas the effects of some will not manifest until the future as malignant disease. Other infections may go unnoticed secondary to a lack of specific histologic findings. Because herpesviruses cause such a wide spectrum of cutaneous conditions, it is prudent that pathologists be aware of the varied clinical and histopathologic presentations so that these infections will not persist undiagnosed. Additionally, methods of virus detection will briefly be reviewed.
