A 4.5-year-old llama was admitted for evaluation of a firm mass rostral and
ventral to the medial canthus of the left eye. Mucopurulent nasal discharg
e and absence of airflow through the left nostril were noted. Radiographs o
f the skull revealed a sharply demarcated soft tissue mass with faint miner
alization. Endoscopy of the nasal passages revealed a mucosa-covered mass o
riginating in the area of the second premolar, extending to the edge of the
soft palate, and obstructing the airway. Examination of the oral cavity re
vealed a missing second molar and a mass protruding 2-cm from the empty alv
eolus. An ossifying fibroma, a previously unreported tumor in llamas, was d
iagnosed at postmortem examination.
