Plain-English summary
A 14-year-old Haflinger gelding had a noticeable growth on the cornea of his right eye. The mass was surgically removed and examined closely by specialists. The initial diagnosis suggested it was a type of cancer called corneal sarcoma, likely a fibrosarcoma, but further tests indicated it was more similar to a malignant peripheral nerve sheath tumor, which is a rare type of tumor in both people and pets. The exact cause of this tumor remains unknown, and there was no evidence of infection with bovine papillomavirus.
Abstract
A 14-year-old Haflinger gelding presented with a protruding mass involving the cornea of the right eye. The mass was resected and submitted for histopathologic and immunohistochemical examination. The preliminary diagnosis was corneal sarcoma, most likely fibrosarcoma. The immunohistochemical results confirmed the mesenchymal origin of the neoplastic cells, which were most consistent with a malignant peripheral nerve sheath tumor. Corneal mesenchymal neoplasms are extremely uncommon tumors in human beings and domestic animals. The cause for this tumor was not determined; infection with bovine papillomavirus was not detected.
