A 2-month-old Turkish Angora cat presented with multiple skin masses after first vaccination and spot-on antiparasitic treatment. There was no hair loss or pruritis, and tests revealed negative for the feline leukemia and immunodeficiency viruses. Biopsy revealed densely packed eosinophils in sparse dermal tissue with a few mast cells. These lesions did not respond promptly to prednisolone treatment, but they regressed without relapse over the following month, despite sequential vaccinations and anti-parasitic treatment. The present case is interesting considering the rarity of multiple eosinophilic granuloma development in a very young cat with a recent history of vaccination and antiparasitic treatment.
