Plain-English summary
A 1-year-old male Pug was brought to the vet because his left eye was bulging out and not responding to treatment. The vet found that the eye was not only protruding but also had some unusual movements and swelling. Scans revealed a large tumor behind the eye that was affecting nearby areas. Unfortunately, after trying to remove the tumor and provide comfort, the dog had to be euthanized 13 weeks later due to worsening health and signs of neurological issues. The tumor was diagnosed as a malignant pigmented peripheral nerve sheath tumor, which is a type of cancer.

Abstract
A 1-year-old male castrated Pug was referred for unilateral exophthalmos unresponsive to oral antibiotic and anti-inflammatory therapy. Clinical findings included exophthalmos of the left eye with lateral strabismus, resistance to retropulsion, and an elevated nictitans. Hematologic and biochemical analyses were within normal limits. Findings following computed tomography (CT) of the head included an expansile retrobulbar soft tissue mass with bony lysis extending into the left nasal cavity and nasopharynx. Ultrasound-guided fine-needle aspirates and biopsy samples obtained via rhinoscopy were nondiagnostic. Palliative exenteration was elected; the patient was euthanized 13 weeks following exenteration due to development of neurologic signs and perceived poor quality of life. The histopathologic diagnosis was a malignant pigmented peripheral nerve sheath tumor.
