Plain-English summary
A 2-year-old female cat had multiple raised, pigmented skin lesions on the right side of her body that had been itchy since she was a kitten. After a thorough examination, the veterinarian found that these lesions were not caused by a viral infection and were diagnosed as epidermal nevi, which are similar to a skin condition seen in humans. While the cat experienced moderate itching, there was no indication of a serious underlying issue. Treatment options for managing the symptoms can be discussed with your veterinarian.

Abstract
Multiple, pigmented, verrucous, cutaneous lesions in a 2-year-old female cat were pathologically examined. The lesions were linearly arranged on the right side of the body, and had developed along with moderate pruritus since infancy. Histologically, prominent exophytic, papillomatous outgrowths of the epidermis and acanthosis with intense ortho and parakeratotic hyperkeratosis were characteristic of the lesions. Dermal inflammation with mononuclear cells, neutrophils, and eosinophils was also noted. Inclusion bodies, cellular degeneration, and intranuclear viral particles suggesting papillomavirus infection in the keratinocytes were not observed. Papillomavirus antigen and DNA were not detected in the lesions by immunohistochemistry and polymerase chain reaction, respectively. In accordance with these clinical and histopathological features, the cutaneous lesions of the present cat were diagnosed as epidermal nevi, which were consistent with human inflammatory linear verrucous epidermal nevi.
