- Better known for its effects in the upper respiratory system, feline herpesvirus-1 can result in ulcerative lesions on the face as well as corneal damage in infected animals. FHV-1 has the ability to become dormant within the trigeminal ganglion and recrudescent infections may result in ulcers on the face, nasal planum, and occasional limbs. These often pruritic lesions often contain numerous eosinophils upon biopsy, which makes the eosinophilic granuloma complex and allergic hypersensitivities very viable ruleouts. Definitive diagnosis requires identification of intranuclear inclusions in degenerating cells at the edges of the ulcer , which is often problematic. Similar, although more severe lesions may be seen in cheetahs.
