Bilateral trigeminal nerve paralysis and Horner's syndrome associated with myelomonocytic neoplasia in a dog.
A 5-year-old male Doberman Pinscher had nasal stenosis, dropped mandible, bilateral atrophy of masseter and temporalis muscles, and Horner's syndrome caused by aleukemic myelomonocytic leukemia. Neoplastic cellular neurotropism, diffuse turbinate and nodular peribronchial infiltrate, and a hepatic portal infiltrative pattern similar to that of lymphoma were microscopic features of interest.
