Gross description
Microscopic (histologic) description
  • Virus present in enlarged endothelium and stromal cells at ulcer base
  • Basophilic cytoplasm often has coarse intracytoplasmic granules
  • Prominent intranuclear basophilic inclusions surrounded by clear halo
  • Macrophage aggregates in perivascular distribution are somewhat specific for CMV or HSV (Hum Pathol 1997;28:375); features are less obvious in patients receiving antiviral therapy
  • Inclusions are generally numerous but may be atypical in HIV patients (Hum Pathol 1992;23:1019)
