| 英文描述 | Cats have developed skin tumors that bear a very close resemblance on histopathology to equine sarcoids and can be difficult to differentiate from schwannomas. Cats affected by this uncommon tumor are often from rural areas. Lesions are primarily on the face and footpads; they do not metastasize, but can recur after excision. Papillomavirus DNA was identified in mesenchymal tumor cells and not in the hyperplastic epithelium. Because the pathogenesis of this lesion is believed to resemble that of equine sarcoids, these tumors were classified as feline sarcoids rather than feline fibropapillomas. |
