Plain-English summary
A 7-year-old female Labrador retriever was brought in for persistent coughing, retching, excessive drooling, and a droopy eye on the left side of her face. After a CT scan showed a mass near her neck, the vet performed surgery to remove a large section of the affected nerve. The tumor was confirmed to be malignant, but thankfully, it hadn't spread to other areas. This case highlights a rare type of tumor affecting dogs, and the surgery was necessary to address the issue.

Abstract
A peripheral nerve sheath tumor was diagnosed in a female, neutered Labrador retriever with a 6 mo history of coughing, retching, ptyalism, and left-sided Horner's syndrome. Computed tomography scan of the neck revealed a mass lesion between the carotid artery and esophagus in the mid-cervical region. Exploratory surgery was performed and an 18 cm section of thickened vagus nerve was excised. Histopathological findings and immunochemistry staining confirmed a malignant peripheral nerve sheath tumor. The tumor showed microscopic signs of malignancy, but there were no macroscopic signs of local extension or distant metastasis. This report documents a peripheral nerve sheath tumor of rare origin in dogs.
