| 英文描述 | A series of dogs was described which had 1-2 cm, circumscribed, flasklike structures below the level of the surrounding normal skin. There was a small pore opening to the surface of the skin. Ages of affected animals varied from 8 months to 3 years. Lesions were located on the ventrum (inguinal region and abdomen). These lesions resembled intracutaneous cornifying epitheliomas, but on histology there were papillary projections of epiermis into the lumen. A papillomavirus of a type different from that seen in oral papillomatosis was seen in the lesions using electron microscopy, and this appears to be a distinct type of papilloma. |
