Article Synopsis
- In spring 2021, 12 first-calving heifers on a Taranaki dairy farm developed severe skin lesions on their teats, leading to varied outcomes: 8 cows recovered while 4 were culled, with two requiring surgical intervention.
- The lesions started as crusty scabs and progressed to thick, dead tissue, causing inflammation without milk leakage or odor; diagnostic tests excluded several viral causes.
- The condition was diagnosed as ischaemic teat necrosis (ITN), resembling a novel disease previously reported in the UK, with additional cases appearing on the same farm in the following years.
Sarcoids are common mesenchymal neoplasms of horses. Although there are few studies in which sarcoids have been followed over a long period of time, sarcoids are considered locally invasive and have been reported to frequently recur following surgical excision. Currently, no histological features have been identified to predict which sarcoids will recur after excision.

- - Medical records of four dogs in New Zealand diagnosed with protothecosis showed varied symptoms including ocular problems, gastrointestinal issues, and skin lesions, confirming a rare but serious condition.
- - Findings revealed severe complications such as panuveitis, retinal detachment, chronic hemorrhagic diarrhea, and skin ulcerations, with diagnosis confirmed through histopathology and PCR tests.
- - Despite initial treatment efforts, only two dogs received specific medication for the infection, leading to the unfortunate decision to euthanize all four due to worsening clinical signs and quality of life concerns.
A raised plaque that contained histological evidence of papillomavirus infection and sequences from a novel papillomavirus type developed close to the ear canal of a 14-year-old West Highland white terrier. The plaque was excised, and further plaques developed within the same area of pinna.

Histology of the superficial aspects of the mass revealed epidermal cells arranged in nests and trabeculae while the deeper parts of the mass consisted of small round cells arranged in sheets or bundles of elongate spindle-shaped cells. A diagnosis of basal cell carcinoma (BCC) was made.
