Plain-English summary
A 14-month-old male neutered domestic shorthaired cat was found to have a small, raised ulcer on its neck, and the vet suspected it might have feline infectious peritonitis (FIP), a serious viral disease. A skin sample was taken for testing, which showed signs of ulcerative dermatitis, meaning the skin was damaged and inflamed, with a buildup of immune cells. Further testing confirmed the presence of the virus in the skin tissue. This case highlights that if a cat has skin lesions along with other signs of illness that could indicate FIP, it’s important to consider this virus as a possible cause. The treatment details and outcome were not provided, but the findings suggest that FIP can lead to skin problems in cats.
Abstract
Feline infectious peritonitis (FIP) is one of the most prevalent viral diseases of wild and domestic cats. Despite of its multisystemic character, cutaneous lesions of FIP have been rarely described. A skin biopsy from a 14-month-old male neutered domestic shorthaired cat with a slightly raised, 5 mm in diameter ulcer on the dorsal cervical area and a presumptive clinical diagnosis of FIP was submitted for histological examination. Histological changes consisted of ulcerative dermatitis with perivascular, periadnexal, and interstitial accumulations of neutrophils, macrophages, lymphocytes, and plasma cells with areas of vasculitis. Immunohistochemistry for feline coronavirus revealed intralesional clusters of antigen within macrophages. FIP should be considered in cases of papular to nodular or ulcerative skin lesions in cats when occurring in conjunction with clinical signs of systemic disease consistent with FIP.
