History

An 8-year-old sexually intact male white alpaca was submitted for necropsy after being referred to a private veterinary hospital because of a history of circling and ataxia for a few hours.

 Clinical and Gross Findings

Physical examination performed by the referring veterinarian did not reveal any other abnormalities, but the clinical signs rapidly progressed and the alpaca died 24 hours later. No neurologic examination was performed. At necropsy, the carcass was in good body condition. A well-demarcated, sessile, white, and firm nodule measuring 3 cm in diameter was attached to the gingival surface of the gum at the level
