Cowdry bodies
Appearance
Cowdry bodies are eosinophilic nuclear inclusions composed of nucleic acid and protein seen in cells infected with Herpes simplex virus or Varicella-zoster virus.
There are two types of intranuclear Cowdry bodies:
- Type A (as seen in herpes infection) [2]
- Type B (as seen in infection with poliovirus), though it may seem that this is an antiquated and perhaps illusory type. [3]
